Answer 1

Answer:

Follow me..

Step-by-step explanation:

Let

The perimeter of a rectangle =P.

The length of a rectangle =l.

The breadth of a rectangle =b.

So,

The perimeter of a rectangle = two times sum of the length and the breadth of a rectangle

=2× (sum of the length and the breadth of a rectangle)

P=2(l+b).
