Question

The perimeter of a rectangle is 440 cms. Can you find the length of the rectangle if the breadth = 70 cms?

• A. 150 cms
• B. 110 cms
• C. 370 cms
• D. 300 cms

Answer 1

The correct option is A

150 cms

Let the length of the rectangle = “p” cms

Perimeter of a rectangle = 2 ( length + breadth )

Hence 2 (p + 70 ) = Perimeter of the given rectangle

Forming an equation:

$2(p+70)=440$

$=2p+140=440$

$=2p=440-140=300$

$=p=\frac{300}{2}=150\text{cms}$
