If the perimeter of a certain rectangle is 76 m and its area is 360 m2, then what is the length of its shortest side ?
Perimeter . = 2(l+b) = 76
i.e. l+b = 38
Area = l*b = 360
:et's think of two numbers whose sum is 38 and whose products is 360 (Instead of making a quadratic equation and creating more difficulty for ourselves)
