Question

The length of a rectangular garden is 9m more than the width if the perimeter is 156m, find the dimensions of the garden. With solution pls.

Answer 1

2[x+(x+9)]=156

Answer 2

2(2x+9) = 156
2x+18 = 78
2x = 78- 18
2x = 60
x = 30

width = 30
Length = 39

Answer 3

4x+18 = 156
4x = 138
x = 138/4
x =34.5

Width = 34.5m
Length = 43.5m

Proof: 34.5*2 + 43.5*2 = 156
