Question

The equation P = 21 + 2w can be used to find the perimeter of a rectangle. A 1 point rectangular shaped playground is enclosed by a fence that is 500 m. The length of the playground is 120 m. Use the equation to determine the width of the playground *

Answer 1

• 130 m

Explanation:

Given:

• P = 2l + 2w
• P = 500 m

Length is:

• l = 120 m

Substitute values and solve for w:

• 500 = 2*120 + 2w
• 2w = 500 - 240
• 2w = 260
• w = 260/2
• w = 130 m
