Question

A rectangular garden is 10 feet longer than it is wide. 

The perimeter (distance around) of the garden is 68 feet. What is the length of the garden?

 

Answer 1

width = x

length = x+10

Perimeter = 2 * length + 2* width

68 = 2x + 2(x+10)

68 = 2x + 2x + 20

68 = 4x + 20

48 = 4x

x = 12
