   Question :–

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

   Given :–

   • Area of rectangle = 650 sq.cm

   • Breadth of rectangle = 13 cm

   To Find :–

   The perimeter of a rectangle

   We have to use formula in this question:

   • Area of rectangle = L × B
   • Area of rectangle = 2 ( L + B )

   Solution :–

   we have ,

   Area of rectangle = 650 sq.cm

   Breadth of rectangle = 13 cm

   By the question ,

   Area = L × B

   ↪650 sq.cm = L × 13 cm

   ↪ 650 sq.cm ÷ 13 cm = L

   ↪ 50 cm = L

   ↪ 50 cm = L

   ∴ Length of rectangle = 50 cm

   And Breadth = 13 cm

   now,

   The perimeter of rectangle

   ↪ 2 ( L + b )

   ↪ 2 ( 50 cm + 13 cm )

   ↪ 2 × 63 cm

   ↪ 126 cm

   Hence,

   The perimeter of rectangle is 126 cm.

2. perimeter of rectangle=2(l+b)

   650 =2(l+13)

   650 = 2l+26

   650- 26= 2l

   624= 2l

   624/2= l

   312 = l answer
