Question

a rectangular swimming pool’s length is 5 meters more than four times it’s width. if the perimeter of the pool is 110 meters, find the dimensions of the pool

Answer 1

width = x

length = 4x+5

110=2(x+4x+5)

110 = 2(5x+5)

110 = 10x+10

-10x=10-110

10x=100

x=10

width = 10m

length = 45m
