Test integer options: $7 \times 24 = 168$. Perimeter $= 2(7 + 24) = 62$.
Let $w$ be the width. The length is $l = 3w + 3$. Area $A = w(3w + 3) = 168\text{ sq ft}$. Dividing by 3 gives $w^2 + w - 56 = 0$. Factoring: $(w + 8)(w - 7) = 0$. Since width must be positive, $w = 7\text{ ft}$. The length is $l = 3(7) + 3...
