The perimeter of a rectangle is 90m. It's length is 1.5 times its width. find the length and width of the rectangle.

Answer provided by our tutors

Let

x = the width

1.5x = the length (1.5 times the width)

P = 90 m the perimeter

Since P = 2(length +width) we have:

P = 2(1.5x + x)

2(1.5x + x) = 90
