Question

Perimeter of a rectangle is given by ________.

• A. 2 Length + Breadth
• B. 2(Length + Breadth)
• C. 2( Length - Breadth)
• D. Length x Breadth

Answer 1

The correct option is B

2(Length + Breadth)

The perimeter is given by the sum of the length of all the sides.

A rectangle has 4 sides and opposite sides are equal in length.

$\Rightarrow \text{Perimeter of a rectangle}\text{= Length + Breadth + Length}\text{+ Breadth}=2\times \text{Length}+2\times \text{Breadth}=\text{2(Length + Breadth)}$
