MCQ

The perimeter of a rectangle is 60 cms. If its length is twice its breadth, then its area is: 

Options

  • 200 cm2 

  • 180 cm2

  • 160 cm2 

  • 220 cm2 

Solution

The perimeter of a rectangle is 60 cms. If its length is twice its breadth, then its area is: 200 cm2 

Explanation:

Let the breadth of the rectangle is b, then the length  of the rectangle is 2b.

Perimeter = 2 (length + breadth)  

60 = 2 (2b + b) 

6b = 60

6b = `60/6` = 10

Area of the rectangle = length × breadth  
= 2b × b = 2b2   
= 2 (10)2 = 200 cm2
