Formula to find perimeter for a rectangle:
length + width + length + width
l + w + l + w
Formula to find area for a rectangle:
length × width
l × w
1.
Perimeter (P): 5 + 2 + 5 + 2 = 14
Area (A): 5 × 2 = 10
2.
P: 6 + 2 + 6 + 2 = 24
A: 6 × 2 = 12
3.
P: 7 + 9 + 7 + 9 = 32
A: 7 × 9 = 63
4.
P: 10 + 8 + 10 + 8 = 36
A: 10 × 8 = 80
5.
P: 10 + 6 + 10 + 6 = 32
A: 10 × 6 = 60
6.
P: 9 + 9 + 9 + 9 = 36
A: 9 × 9 = 81
7.
P: 10 + 3 + 10 + 3 = 26
A: 10 × 3 = 30
8.
P: 7 + 7 + 7 + 7 = 28
A: 7 × 7 = 49
9.
P: 6 + 7 + 6 + 7 = 26
A: 6 × 7 = 42
Area will always have its units squared (cm^2) because the formula requires we multiply the numbers and therefore the units: cm × cm = cm^2

Estimation on a scale drawing of a fence, 3.75 inches represent 24 feet . what. is the actual length of a second fence is 2.8 inches in the drawing?
The exact length of the second fence is __ feet.
Answers
Answer: 17.92 feet
Step-by-step explanation:
From the question, we are informed that the estimation on a scale drawing of a fence is that 3.75 inches = 24 feet.
Based on the above, 1 inch will be:
= 24/3.75
= 6.4 feet
Therefore, the actual length of a second fence that is 2.8 inches in the drawing will be:
= 6.4 × 2.8
= 17.92 feet

Answer:
∠H = 50°∠A = 80°∠W = 130°Step-by-step explanation:
It is helpful to remember that opposite angles of an inscribed quadrilateral are supplementary. This lets you find the value of m.
∠A +∠K = 180°
8m° +10m° = 180°
18m = 180
m = 180/18 = 10
Using this value we can find ...
∠H = 5m° = 5·10° = 50°
∠A = 8m° = 8·10° = 80°
∠W = 180° -∠H = 180° -50° = 130°

On a snowy winters eve two candles are lit at the exact same time. A 18-inch candle and a 21-inch candle are lit at the exact same time. The 18-inch candle burns 2 inches every hour. The 21-inch candle burns 3 inches every hour. Create a system of equations using the information
Answers
Answer:
y=21-3x and y=18-2x
Step-by-step explanation:
Ok, so we have candle A, which is 21 inches and burns 3 inches every hour. in slope-intercept form, the hours would be the x, the 21 is our y intercept. So the first equatio would be y=-3x+21 (negative slope, because the height of the candle is going down). Candle b, which is 18 inches, burns away 2 inches each hour. We can make -2 the slope (negative 2, since the candle is being burned away, not being added to), and the 18 our y intercept. So the two equations would be
y=21-3x
and
y=18-2x

1. Leslie visits a local department store in order to purchase summer clothes. The
price of the dress is $40. The dress is marked up 25%. What is the selling price of
the dress?
Answers
Answer:
$50
Step-by-step explanation:
Given data
We are given that the price is $40
the markup percent is 25%
Hence the price will be
40+25% of 40
=40+ 25/100*40
=40+ 0.25*40
=40+10
=$50
Therefore, the price of the dress is $50
A piece of rural land sold ten years ago for 40000. The price for the same land this year is $800 more per acre, and it sold for 60000. What is the size of the piece of land in acres?
Answers
Answer: 25
Step-by-step explanation:
From the question, we are informed that the piece of rural land sold ten years ago for 40000 and that the price for the same land this year is $800 more per acre, and it sold for 60000.
The size of the piece of land in acres will then be:
40000 + 800x = 60000
800x = 60000 - 40000
800x = 20000
x = 20000/800
x = 25
The land is 25 acres
Answer: 25
Step-by-step explanation:
40000 + 800x = 60000800x = 60000 - 40000800x = 20000x = 20000/800x = 25

(a) The length and breadth of the playground as measured by the surveyor are 20 m and 13 m respectively to nearest metre.
Since the actual length is x m and breadth is y m, then;
i. x ≥ 20 m or x ≤ 20 m
ii. y ≥ 13 m or y ≤ 13 m
(b) perimeter of the playground = 2 (length + breadth)
= 2 ( 20 + 13)
= 2 x 33
= 66 m
The range of values of the perimeter = 65.4 m < perimeter < 66.5 m
ii. area of the playground = length x breadth
= 20 x 13
= 260 [tex]m^{2}[/tex]
The range of values of the area = 259.4 [tex]m^{2}[/tex] < Area < 260.5 [tex]m^{2}[/tex]
