Question

How do you solve this ?

Answer 1

The length is w+8 and the width is w.
Perimeter= 2(w+l)

256= 2(w+8+w)
256= 2(2w+8)
256= 4w+16
240= 4w
60= w

Final answer: Width= 60 ft, Length= 68 ft

Answer 2

width = w

length = w+8

perimieter = 256 feet

formla for perimeter is p=2L+2w

so you have: 256 =2(w+8) +2w =

256 = 2w+16 +2w

256= 4w+16

240=4w

w=240/4 = 60

width is 60 feet

length = 60+8 = 68 feet
