A rectangle is shown. The length of the rectangle is labeled as 8 cm, and the width is labeled as 6 cm. What will be the perimeter and the area of the rectangle below if it is enlarged using a scale factor of 4.5? (5 points)


Perimeter = 46 cm, area = 131.25 cm2
Perimeter = 126 cm, area = 972 cm2
Perimeter = 46 cm, area = 972 cm2
Perimeter = 126 cm, area = 131.25 cm2
Perimeter = 46 cm, area = 131.25 cm2
Perimeter = 126 cm, area = 972 cm2
Perimeter = 46 cm, area = 972 cm2
Perimeter = 126 cm, area = 131.25 cm2

Answers

Answer 1

Answer:

Perimeter = 126cm

Area = 972cm^2

Step-by-step explanation:

6*4.5 = 27

8*4.5 = 36

Perimeter = 27*2+36*2= 126 cm

Area = 27*36 = 972 cm^2

Hope this helped!

Answer 2

Answer:

Perimeter = 126 cm, area = 972 cm2

Step-by-step explanation:

Rectangle perimeter:

P = 2(w + l)

Rectangle area:

A = wl

When scaled, the perimeter will change by same factor but the area by the square of same factor.

Applying to the given rectangle

Perimeter:

P = 2(6 + 8)(4.5) = 126 cm

Area:

A = 6*8*4.5² = 972 cm²

Correct choice is B

What is the ratio in which the point P(3/4,5/12) decides the line segment joining points A(1/2,3/2) and B(2,-5)

Answers

Given:

The point [tex]P\left(\dfrac{3}{4},\dfrac{5}{12}\right)[/tex] divides the line segment joining points [tex]A\left(\dfrac{1}{2},\dfrac{3}{2}\right)[/tex] and [tex]B(2,-5)[/tex].

To find:

The ratio in which he point P divides the segment AB.

Solution:

Section formula: If a point divides a segment in m:n, then the coordinates of that point are,

[tex]Point=\left(\dfrac{mx_2+nx_1}{m+n},\dfrac{my_2+ny_1}{m+n}\right)[/tex]

Let point P divides the segment AB in m:n. Then by using the section formula, we get

[tex]\left(\dfrac{3}{4},\dfrac{5}{12}\right)=\left(\dfrac{m(2)+n(\dfrac{1}{2})}{m+n},\dfrac{m(-5)+n(\dfrac{3}{2})}{m+n}\right)[/tex]

[tex]\left(\dfrac{3}{4},\dfrac{5}{12}\right)=\left(\dfrac{2m+\dfrac{n}{2}}{m+n},\dfrac{-5m+\dfrac{3n}{2}}{m+n}\right)[/tex]

On comparing both sides, we get

[tex]\dfrac{3}{4}=\dfrac{2m+\dfrac{n}{2}}{m+n}[/tex]

[tex]\dfrac{3}{4}(m+n)=\dfrac{4m+n}{2}[/tex]

Multiply both sides by 4.

[tex]3(m+n)=2(4m+n)[/tex]

[tex]3m+3n=8m+2n[/tex]

[tex]3n-2n=8m-3m[/tex]

[tex]n=5m[/tex]

It can be written as

[tex]\dfrac{1}{5}=\dfrac{m}{n}[/tex]

[tex]1:5=m:n[/tex]

Therefore, the point P divides the line segment AB in 1:5.

Use the triangle below to find cos V.

Answers

Answer:

[tex]cos\ V = \frac{2\sqrt{29}}{29}[/tex]

Step-by-step explanation:

Given

The attached triangle

Required

Find cos V

In trigonometry:

[tex]cos\theta = \frac{Adjacent}{Hypotenuse}[/tex]

In this case:

[tex]cos V= \frac{TV}{UV}[/tex]

Where

[tex]TV = 6[/tex]

and

[tex]UV^2 = TV^2 + TU^2[/tex] -- Pythagoras

[tex]UV^2 = 6^2 + 15^2[/tex]

[tex]UV^2 = 261[/tex]

Take square roots

[tex]UV = \sqrt{261[/tex]

[tex]UV = \sqrt{9*29[/tex]

[tex]UV = \sqrt{9} *\sqrt{29[/tex]

[tex]UV = 3\sqrt{29[/tex]

So:

[tex]cos V= \frac{TV}{UV}[/tex]

[tex]cos\ V = \frac{6}{3\sqrt{29}}[/tex]

[tex]cos\ V = \frac{2}{\sqrt{29}}[/tex]

Rationalize:

[tex]cos\ V = \frac{2}{\sqrt{29}}*\frac{\sqrt{29}}{\sqrt{29}}[/tex]

[tex]cos\ V = \frac{2\sqrt{29}}{29}[/tex]
