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
