Answer 2

Answer:

Given :

Area of rectangle is 400 cm.

Lenght of rectangle = 40 cm

To find :

The perimeter of rectangle =?

Formula Used :

Area of Rectangle = length x breadth

Perimeter of the rectangle = 2( length + breadth)

Step-by-step explanation :

As it is Given that,

Area of rectangle is 400 cm.

Lenght of rectangle = 40 cm

We know that,

Area of Rectangle = length x breadth

Substituting the values in the above formula, we get,

400 = 40 × breadth

breadth = 400/40

breadth = 10

Therefore, Breadth of the rectangle = 10 cm.

Now,

As We know that,

Perimeter of the rectangle = 2(length + breadth)

Substituting the values in the above formula, we get,

= 2(40 + 10)

= 2(50)

= 100.

Therefore, Perimeter of the rectangle = 100 cm.
