Question

The perimeter of a rectangle is 30 inches. The length is 3 more than the width. What is the length and width of the rectangle?

Answer 1

Let x = the width of the rectangle

Let x+3 = the length of the rectangle

The perimeter is 2Length + 2Width = 2(x+3) + 2x = 30 = 4x + 6

Simplifying, we get 4x = 24 or x = 6

So Length = 6+3+ 9

Width = 6
