Question

The perimeter of a rectangle is 220 cms. Can you find the length of the rectangle if breadth = 35 cms?

• A. 55 cms
• B. 75 cms
• C. 70 cms
• D. 150 cms

Answer 1

The correct option is B

75 cms

Let the length of the rectangle = “p” cms

Perimeter of a rectangle = 2 ( length + breadth )

Hence 2 (p + 35 ) = Perimeter of the given rectangle

Forming an equation:

$2(p+35)=220$

$=2p+70=220$

$\Rightarrow 2p=220-70=150$

$\Rightarrow p=\frac{150}{2}=75\text{cms}$
