Answer:

The dimension is 45.5x79.5 ft

Step-by-step explanation:

let the width be w

the length = w-34

perimeter= 250ft

we know that the expression for perimeter is

p=2l+2w

250=2(w-34)+2w

250=2w-68+2w

250=4w-68

250+68=4w

318=4w

w=318/4

w=79.5

we know that length is

l=w-34

l=79.5-34

l=45.5
