Question

The length of a rectangular piece of land is 4ft more than two times its width. The perimeter is 32ft. find the dimensions

Answer 1

L = 2w + 4

p = 2w + 2L

32 = 2w + 2(2w + 4)

32= 2w + 4w + 8

24 = 6w

4 = w


Now,

p = 2w + 2L
32 = 2(4) + 2L
32= 8 + 2L
24 = 2L
12 = L

check
p= 2w + 2L
32 = 2(4) + 2(12)
32 = 8 +24
32 = 32
