Question

The perimeter of a rectangle is equal to $2$ times the sum of its length and breadth. Write its expression.

Answer 1

Here given that,

The perimeter of a rectangle is equal to $2$ times the sum of its length and breadth

So, let the length be $l$ m

And breadth is $b$m

Now sum of length and breadth = $(l+b)$ m

And $2$ times of it = $2(l+b)$ m

Hence, the expression for perimeter is $2(l+b)$ m
