Question

Chloe is installing new windows in her house and needs to determine the amount of sealant she will need around the outside edge of each rectangular window. Each of the windows has an area of 2,160^2 with a length of 60 inches. What is the perimeter of each window? To find the width of each window, use the formula w=A/l, where w represents the width, A represents the area, and l represents the length. To find the perimeter, use the formula P=2l+2w, where P represents the perimeter, l represents the length, and w represents the width.
18 inches
36 inches
96 inches
192 inches

Answer 1

Answer:

192 inches

Step-by-step explanation:

In order to calculate the perimeter of each window, you have to first calculate the height of the window, by using the formula:

H=$\frac{Area}{Length}$

H=$\frac{2160}{60}$

H= 36

Now that you have the height you just calculate the perimeter by adding all the sides of the rectangle:

2h +2 l= P

P= 2(36)+ 2(60)

p= 72+ 120

P= 192

The answer for the perimeter of the window is 192 inches.

Answer 2

36 inches is the correct answer
