Answer: 118 feet

Step-by-step explanation:

For a rectangular shape: Area = W × L

450 = 9 × L

450 ÷ 9

L = 50

Perimeter of a rectangular shape = 2L + 2W

Perimeter = (2 × 50) + (2 × 9)

= 100 + 18 = 118 feet

The length of the garden is 50 feet then he needs to buy to enclose the garden on all four sides by fencing is 118 feet.

What is a rectangle?

It is a polygon that has four sides. The sum of the internal angle is 360 degrees. In a rectangle, opposite sides are parallel and equal and each angle is 90 degrees. And its diagonals are also equal and intersect at the mid-point.

The area of Miguel's rectangular garden is 450 square feet.

The garden is 9 feet wide.

Let the length of the garden be L. Then we have

Area = LW

9L = 450

 L = 50

Then the perimeter of Miguel's garden will be

Perimeter = 2L + 2W

Perimeter = 2 × 50 + 2 × 9

Perimeter = 100 + 18

Perimeter = 118
