Question

The perimeter of a rectangle is 75 cm. Its

3
length is 2 – times its breadth. Find the
4.
length and breadth of the rectangle.

Answer 1

length = 25 cm , breadth = 12.5 cm

Explanation:

let the breadth be b then the length = 2b

The perimeter is the sum of the 4 sides and is equal to 75 , then

b + b + 2b + 2b = 75 , that is

6b = 75 ( divide both sides by 6 )

b = 12.5

Then

breadth = 12.5 cm and length = 2 × 12.5 = 25 cm
