The correct answer is C.
The rectangle is made of 7 equal squares. Therefore, the ratio of the width and length of the rectangle is 1 to 7. Why?
Let X be the width of the rectangle. So,
\(X × 7X = 567 → 7X^2 = 567 → X^2 = 81 → X = 9\)
The width of the rectangle is 9 feet and the length is 63 feet.
(7 × 9 = 63)
The perimeter of the rectangle is:
2 × (9 + 63) = 144 feetThe Best Books to Ace Algebra
