Question

The perimeter of a rectangle is 38 units. The length is 13 units longer than the width. What are the dimensions of the rectangle?

Answer 1

Length = x+13=6+13=19units

Explanation:

P = 2(l +w)

Let width be x

Length = x + 13

P = 38

38 = 2(x + 13 + x)

38 = 2(2x + 13)

38 = 2x + 26

2x = 38 - 26

2x = 12

x = 12/2

x = 6unit

Width = 6units

Length = x + 13 = 6+13 = 19units

Answer 2

3 units ×16 units
