A rectangle has an area of 248m2.
One of the sides is 4m in length.
Work out the perimeter of the rectangle.
Step-by-step explanation:
In a rectangle
Area (A) = 248 m²
length (L) = 4 m
breadth (b) = ?
We know
A = L * b
248 = 4 * b
b = 62 m
Now
Perimeter of the rectangle
= 2 ( L + b)
= 2 ( 4 + 62)
= 2 * 66
= 132 m
Hope it will help :)
Answer:
first we have to get the width.
A=L*w
so, A =L *W
L L
W=A
L
248m²=4m*W
248m²=4m*w
4m 4m
w=248m²
4m
w=32m
now we can find the perimeter.
p=2(L+w)
p=2(4m+32m)
p=2(36m)
p=72m
there for the answer is 72m

A rectangular swimming pool is twice as long as it is wide. A small concrete walkway surrounds the pool. The walkway is a 2 feet wide and has an area of 448 square feet including the pool.Find the dimensions of the pool
Answer:
The width and the length of the pool are 12 ft and 24 ft respectively.
Step-by-step explanation:
The length (L) of the rectangular swimming pool is twice its wide (W):
[tex] L_{1} = 2W_{1} [/tex]
Also, the area of the walkway of 2 feet wide is 448:
[tex] W_{2} = 2 ft [/tex]
[tex] A_{T} = W_{2}*L_{2} = 448 ft^{2} [/tex]
Where 1 is for the swimming pool (lower rectangle) and 2 is for the walkway more the pool (bigger rectangle).
The total area is related to the pool area and the walkway area as follows:
[tex] A_{T} = A_{1} + A_{w} [/tex] (1)
The area of the pool is given by:
[tex] A_{1} = L_{1}*W_{1} [/tex]
[tex] A_{1} = (2W_{1})*W_{1} = 2W_{1}^{2} [/tex] (2)
And the area of the walkway is:
[tex] A_{w} = 2(L_{2}*2 + W_{1}*2) = 4L_{2} + 4W_{1} [/tex] (3)
Where the length of the bigger rectangle is related to the lower rectangle as follows:
[tex] L_{2} = 4 + L_{1} = 4 + 2W_{1} [/tex] (4)
By entering equations (4), (3), and (2) into equation (1) we have:
[tex] A_{T} = A_{1} + A_{w} [/tex]
[tex]A_{T} = 2W_{1}^{2} + 4L_{2} + 4W_{1}[/tex]
[tex]448 = 2W_{1}^{2} + 4(4 + 2W_{1}) + 4W_{1}[/tex]
[tex] 224 = W_{1}^{2} + 8 + 4W_{1} + 2W_{1} [/tex]
[tex] 224 = W_{1}^{2} + 8 + 6W_{1} [/tex]
By solving the above quadratic equation we have:
W₁ = 12 ft
Hence, the width of the pool is 12 feet, and the length is:
[tex] L_{1} = 2W_{1} = 2*12 ft = 24 ft [/tex]
Therefore, the width and the length of the pool are 12 ft and 24 ft respectively.
I hope it helps you!
7) On a farm, there are some cows and birds.
There are 35 total heads and 110 total
legs. How many cows and how many
birds are there?
Answer:
Step-by-step explanation:
"On a farm, there are some cows and birds."
c and b are the number of cows and birds, respectively.
"There are 35 total heads"
c+b = 35
b = 35-c
"110 total legs."
4c + 2b = 110
4c + 2(35-c) = 110
4c + 70 - 2c = 110
2c = 40
c = 20
b = 35-c = 15
20 cows and 15 birds.

Answer: Choice A. (8, 4)
==========================================================
Explanation:
Because x = 2y, we can replace every copy of x with 2y
Let's do so in the second equation
3x - 4y = 8
3(x) - 4y = 8
3(2y) - 4y = 8 .... x replaced with 2y; now let's isolate y
6y - 4y = 8
2y = 8
y = 8/2 ..... divide both sides by 2
y = 4
Use this y value to find x
x = 2y
x = 2*4
x = 8
So we have x = 8 and y = 4 pair together to get the answer (x,y) = (8, 4) which is choice A.

The value of WZ of the rectangle is WZ = 29 units
What is the Perimeter of a Rectangle?The perimeter P of a rectangle is given by the formula, P=2 ( L + W) , where L is the length and W is the width of the rectangle.
Perimeter P of rectangle = 2 ( Length + Width )
Given data ,
Let the length of the rectangle be represented as L
The measure of side WZ = 7x - 6
The measure of side XY = 3x + 14
Now , for a rectangle , the two parallel sides are having similar lengths
So , the measure of side WZ = measure of side XY
Substituting the values in the equation , we get
7x - 6 = 3x + 14
On simplifying the equation , we get
Subtracting 3x on both sides of the equation , we get
4x - 6 = 14
Adding 3 on both sides of the equation , we get
4x = 20
Divide by 4 on both sides of the equation , we get
x = 20/4
x = 5 units
Now , the measure of side WZ = 7x - 6
The measure of side WZ = 7 ( 5 ) - 6
The measure of side WZ = 35 - 5 = 29 units
Hence , the measure of side WZ is 29 units

Answer:
1) m∠U = 90°
2) m∠C = 80°
Step-by-step explanation:
1) The given figure is a quadrilateral
The sum of the interior angles of quadrilateral = 360°
∴ The sum of the interior angles of the given figure = 360°
Therefore, we have;
80° + 24·x + 4 + 6 + 21·x + 90° = 360°
80° + 45·x + 10 + 90° = 360°
x = (360°- (80° + 10° + 90°))/45 = 4
x = 4
m∠U = 6 + 21·x = 6 + 21 × 4 = 90
m∠U = 90°
2) The sum of the interior angles of the given quadrilateral = 360°
∴ 21·x + 6 + 20·x + 24·x + 4 + 21·x + 6 = 360°
86·x + 16 = 360°
x = (360° - 16°)/86 = 4
x = 4
m∠C = 20·x = 20 × 4 = 80
m∠C = 80°
3) In the figure, some angles are left out, therefore, more information on the remaining angles required

Which equation represents a line that passes through (2, -1/2) and has a slope of 3?
A) y-2=3(x+1/2). B)y-3=2(x+1/2)
C)y+1/2=3(x-2)
D)y+1/2=2(x-3)
Answer:
C
Step-by-step explanation:
The line passes through the point (2, -1/2) and has a slope of 3.
We can use the point-slope form, given by:
[tex]y-y_1=m(x-x_1)[/tex]
Where (x₁, y₁) is a point, and m is the slope.
Let (2, -1/2) be (x₁, y₁). We will substitute 3 for m. Therefore:
[tex]\displaystyle y-\Big(-\frac{1}{2}\Big)=3(x-(2))[/tex]
Simplify:
[tex]\displaystyle y+\frac{1}{2}=3(x-2)[/tex]
Therefore, our answer is C.
