Question

The length of a rectangle is twice the with. If the perimeter of the rectangle is 60 units, find the area of the garden

Answer 1

w - width

2w - length

60 - perimeter

w + w + 2w + 2w = 6w - perimeter

The equation:

6w = 60    divide both sides by 6

w = 10 → 2w = 2 · 10 = 20

The area: A = width × length

A = (10)(20) = 200

Answer: The area of the garden is equal 200 square units.
