The length of a rectangular pool is 4 meters less than twice

The length of a rectangular pool is 4 meters less than twice the width. If the pool\'s perimeter is 76 meters, what is the width?

Solution

Let the width of pool be x

Length of pool = 2x-4

Perimeter of pool = 76

2(l+b) = 76

2(2x-4+x) = 76

3x - 4 = 38

x = ,42/3

x = 14

Width of pool = 14 m
