Question 802889: The perimeter of a rectangle swimming pool is 60m. The length of the pool is 4m more than the width. What is the width of the pool?

let the width be W
and since the perimeter P of a rectangle = 2L + 2W
then 60 = 2L + 2W
L is given as W + 4
thus 60 = 2(W + 4) + 2W
simplified,
60 = 2W + 8 + 2W
60 - 8 = 52 = 4W
52/4 = W
