Answer 2

Answer:

Heya mate ☺ ☺!!

Here is ur answer...

Let the breadth of the rectangle is b cm.

So, the length of the rectangle is 2b cm.

We know that the perimeter of rectangle is

=2(l+b)

Since, perimeter of rectangle is 120 cm.

Therefore,

6b=120

b=20 cm

And l=40 cm

So, the area of rectangle is

=20×40=800 cm2

Hence, the length is 40 cm, breadth is 20 cm and area is 800 cm2.

Hope it helps....
