Question

The length of the rectangle is three times the width. The perimeter of the rectangle is 75 in. Find

the length and the width.​

Answer 1

Width = 9.375 in

Length = 28.125 in

Explanation:

Width = x

Length = 3x

Perimeter = 75 in

2 * ( length + width) = 75

2 * (3x + x) = 75

4x = 75/2 = 37.5

x = 37.5/4 = 9.375

Width = 9.375 in

Length = 3 * 9.375 = 28.125 in
