Question

He perimeter of a square is twice the perimeter of a rectangle. If the perimeter of a square is 48 cms and the length of the rectangle is 7 cm. Find the breadth of the rectangle?

Answer 1

Perimeter of square = 48cm

The perimeter of a square is twice the perimeter of a rectangle.

Therefore, the perimeter of rectangle = 48/2 = 24cm

Length = 7cm

Breadth = let it be b

So, breadth = 2l +2b =24

                   => 14 + 2b = 24

                   => 2b = 28

                   => b = 28/2 = 14cm
