Question

Find the perimeter of a rectangle whose area is 650sq cm and its breadth is 13cm

Answer 1

Given:

• Area of rectangle = 650 cm²

• Breadth, b = 13 cm

To find out:

Find the perimeter of a rectangle?

Formula used:

• Area of rectangle = length × breadth

• Perimeter of rectangle = 2 ( l + b )

Solution:

Let the length be l

According to the question,

Area of rectangle = length × breadth

=> 650 = l × 13

=> l = 650/13

=> l = 50

Now,

Perimeter of rectangle = 2 ( l + b )

= 2 ( 50 + 13 )

= 2 × 63

= 126 cm

Hence, the perimeter of rectangle is 126 cm.
