If the perimeter of a certain rectangle is 50 units and its area is 150 sq. units, then how many units is the length of its shorter side?

9 12 10 15

10

We know that, Perimeter of the rectangle = 2(l + b) 2 (l + b) = 50 = (l + b) = 25 Put l = 15 and b = 10, then , Area of the rectangle = lb = 10 × 15 = 150 (satisfied) So, the length of breadth  = 10 cm
