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?
Answer & explanation
Correct answer: option 3
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
