The ratio between the lenght and the breadth of a rectangle is 2 : 1. If breadth is 5 cm less than the length, what will be the parimeter of the rectangle?
Correct Answer: 30 cm
Explanation:
Let length = 2x and breadth = x
According to the question,
2x - x = 5
⇒ x = 5 ∴ Required perimeter = 2(2x + x)
= 6x
= 30 cm
