Question

find the area of rectangle and its length if the perimeter of rectangle is 120 cm and breadth of the rectangle is 40 cm ​

Answer 1

Answer:

Area is 800 cm^2 and the length is 20 cm.

Step-by-step explanation:

We know the perimeter of the rectangle is 120 cm and the breadth of the rectangles is 40 cm.

Therefore the length is,

= (p - 2b)/2

= (120 - 80)/2

= 20 cm.

So, area is = 20 * 40 cm^2

= 800 cm^2.
