Question

The perimeter of a rectangle of length $l$ and breadth $b$ is given by:

• A. $2(l+b)$
• B. $4(l+b)$
• C. $l\times b$
• D. $l^{2}b$

Answer 1

The correct option is A $2(l+b)$

The perimeter of a rectangle is the sum of lengths of all the sides.
In a rectangle, the opposite sides are equal. So,the perimeter is equal to $l+l+b+b$ = $2l+2b$
$\Rightarrow 2(l+b)$
