Answer: H
Explanation:
You're tryna find the area of the wall
Which is the whole surface area minus the door's area
Whole surface area = 8.5 x 12.5 = 106.25
Door area = 5 x 6.75 = 33.75
106.25-33.75 = 72.5 ft^2
ALSO REMEMBER ITS FEET SQUARED
Units are very important just to let you know especially in physics
If you don't get the units to be same then its going to be one heck of a problem
