The area of a square is 36 square feet. If each side is lengthened by 4 feet, how could the perimeter of the new square be calculated?
A.
Divide 36 by 4 to get 9. Then add 4 to 9 to get 13 and multiply this by 4 to get the new perimeter.
B.
Divide 36 by 4 to get 9. Then add 4 to 9 to get 13 and multiply this by 13 to get the new perimeter.
C.
An area of 36 means the original square was 6 feet long on a side. Add 4 to 6 to get 10. Then multiply by 4 to get the new perimeter.
D.
An area of 36 means the original square was 6 feet long on a side. So its perimeter was 24 feet. Add 4 feet to this to get the new perimeter.
