Problema Solution
The perimeter of a rectangular shaped swimming pool is 158 meters. If the width is 9 feet less than the length, how long are the width and length of the pool?
Answer provided by our tutors
P = 2 (+b)
P=2(l+l) =158
= 2 (x +(x-9)) =158
=(x+x -9) = 79
2x =70
x =35
x-9 35 -9 26
length = 35
width = 26
