Problema Solution
The perimeter of a rectangular pool is 140 yd. if the length is 10 yd more than the width,find the width and length
Answer provided by our tutors
let
w = the width of the pool
l = the length of the pool
the perimeter of a rectangular pool is 140 yd:
2(w + l) = 140 divide both sides by 2
w + l = 70
the length is 10 yd more than the width:
l = 10 + w
by solving the system of equations:
w + l = 70
l = 10 + w
we find:
l = 40 yd
w = 30 yd

the width is 30 yards and the length is 40 yards.
