40ft by 60ft​

Answer 1

Answer:

Perimeter = 2 × (length + width) -------(1)

Let width be w

Given length is 20ft longer than width, L = 20 + w

substitute L and w in (1)

perimeter = 2× ( 20 + w + w)

100 = 2 ×(20 + 2w)

50 = 20 + 2w

30 = 2w

w= 15feet

L = 20 + w = 20 + 15 = 35feet

option 1)  15 ft by 35ft

Answer 2

Answer:

15 ft by 35 ft

Step-by-step explanation:

15 + 15 + 35 +35
