Question

The length of a rectangular vegetable bed is 3 feet more than twice the width. The length of the fence around the bed is 36 feet. Find the length and width, and a specific equation to find it if the width is x.

Answer 1

width= 5

length=13

equation (x is rectangle) = 18=(2x+3)+x

Explanation:

Answer 2

width = 5 feet

length = 13 feet

Explanation:

length of a rectangular vegetable bed is 3 feet more than twice the width

l = 2x + 3

length of the fence around the bed is 36 feet

p = 2(l + x)

36 = 2(l + x)

18 = l + x

Substitute for l

18 = (2x + 3) + x

18 = 3x + 3

15 = 3x

x = 5

l = 2(5) + 3 = 13
