Question

Sawyer wants to fence in a rectangular spot for his garden. If he has 92 feet of fencing and works the length of the garden to be five feet less than twice it's width, what will be the area of the garden?

Answer 1

Answer: the area of the garden is 493 ft²

Step-by-step explanation:

Let L represent the length of the rectangular garden.

Let W represent the width of the rectangular garden.

The formula for determining the perimeter of a rectangle is expressed as

Perimeter = 2(L + W)

If he has 92 feet of fencing, it means that

2(L + W) = 92

Dividing through by 2, it becomes

L + W = 46 - - - - - - - - - - - -1

He wants the length of the garden to be five feet less than twice its width. This means that

L = 2W - 5

Substituting L = 2W - 5 into equation 1, it becomes

2W - 5 + W = 46

2W + W = 46 + 5

3W = 51

W = 51/3

W = 17 feet

L = 2W - 5 = 2 × 17 - 5

L = 29 feet

The area of the garden is

LW = 29 × 17 = 493 ft²
