Question

calculate the perimeter of rectangle whose area is 650 square cm and its breadth is 13 cm

Answer 1

Let the length of the rectangle be 'l' cm
Area of the rectangle=650 sq.cm
Breadth of the rectangle=13cm
Area of rectangle=650=lx13
l=50cm
Perimeter of the rectangle=2(l+b)
=2(63)
=126cm

Answer 2

Answer:

126 cm

Step-by-step explanation:

Perimeter of a rectangle = 2 ( l + b )

Area of rectangle = l × b

Given that, Area = 650 cm² and Breadth = 13 cm

⇒ Length × Breadth = Area

⇒ Length = Area / Breadth

⇒ Length = 650 / 13 = 50 cm

Hence Length is 50 cm.

⇒ Perimeter = 2 ( l + b )

⇒ Perimeter = 2 ( 50 + 13 )

⇒ Perimeter = 2 ( 63 )

⇒ Perimeter = 126 cm

This is the required answer.
