Class 7MathematicsSimple Equations

The length of a rectangle is twice its breadth. If its perimeter is 60 cm, find the length and the breadth of the rectangle.

Verified Answer

Let the breadth of the rectangle be x cm.

its length = 2x

Perimeter = 2 (length + breadth) = 2(2x + x) = 2 × 3x = 6x

As per the condition of the question, we have

6x = 60 ⇒ x = 10

Thus the required breadth = 10 cm

and the length = 10 × 2 = 20 cm.
