If I had a yard that was 100 feet by 100 feet, and a house in the middle of it that was 20 feet by 20 feet, what is the area of the yard, not including the house?

Answer:
C. 10000-400 = 9600 square feet
Step-by-step explanation:
The area of a square is s^2, so the area of the yard is 100^2=10000. The area of the house is 20^2=400. Since we do not include the area of the house, 10000-400=9600 square feet.
