The diagram below shows a wall with a
window in Alejandra's room.

Alejandra plans to cover the wall with
wallpaper. How many square feet of
wallpaper will she need?

F. 151.125 ft²
G. 147 ft²
H. 131.125 ft²
J. 135 ft²

 H (131.125 ft^2)

Step-by-step explanation:

first, you need to find the area of the wall

wall:

A=Lw  (length times width)

A= 9.75 x 15.5  (I changed them into decimals)

A = 151.125

now you need to find the area of the window

window:

A = Lw

A = 4 x 5

A = 20

now you need to subtract the area of the window from the area of the wall to find the amount of space you need to cover with wallpaper

151.125 - 20 = 131.125

First, find the area of the lacrosse field on the drawing. It is a rectangle, so you can just multiply the length and width:
A=5.5*3
A=16.5 in. squared

If 1 inch represents 20 yards, then 1 inch squared is going to represent 400 yards squared for area. Now we can set up a ratio:
16.5/x=1/400
x=6,600 yards squared
