Question

The length of a rectangle is 5m longer than its width. If the perimeter of the rectangle is 54m, find its length and width.

Answer 1

Width=11

Length=16

Explanation:

P=2L+2W

54=2(5+w)+2w

Open the brackets

10+2w+2w=54

10+4w=54

Collect the like terms

4w=54-10

4w/4w=44/4

W=11

Since the length is 5m longer

Therefore:11+5=16

Width=11

Length=16
