Answer:  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
