If the perimeter of a certain rectangle is 50 units and its area is 150 sq. units, then how many units are the length of its shorter side?
Show answer & explanation
Correct answer: C
Explanation
The correct answer is Option 3 i.e. 10 units
Let the length and breadth of the rectangle be 'l' and 'b'.
⇒ 2(l + b) = 50
⇒ l + b = 25 units
⇒ l × b = 150
⇒ l = 10/15 units, b = 15/10 units
The length of the shorter side is 10 units.
