Question

The length of a rectangle is twice it’s with the perimeter of a rectangle is 126 feet.

Answer 1

Length = 42 feet

Width = 21 feet

Explanation:

Let the length and width be represented by L and W

L = 2W

Perimeter (P) = 126 feet

2(L + W) = 126

L + W = 126/2 = 63

2W + W = 63

3W = 63

W = 63/3 = 21 feet

L = 2W = 2 × 21 feet = 42 feet
