Answer

Width = 11 Length = 8 + 11 = 19

Work Step by Step

Perimeter = 2(length + width) Perimeter = 60 feet Length = 8 + width (given) Replacing in formula Perimeter = 2((8 + width) + width) 60 = 2(8 + 2width) $\frac{60}{2}$ = (8 + 2width) 30 = 8 + 2width 30 - 8 = 2width 22 = 2 width $\frac{22}{2}$ = 2 width Width = 11 Length = 8 + 11 = 19
