Question

The area of a rectangle is $154c{m}^2$. If the breadth of the rectangle is 14 cm, then the perimeter of the rectangle is:

• A. 100 cm
• B. 25 cm
• C. 44 cm
• D. 50 cm

Answer 1

The correct option is D 50 cm

Given,
$\text{Area}=154c{m}^2\text{Breadth}=14cm\text{Length × Breadth}=\text{Area}\Rightarrow l\times 14=154\Rightarrow l=(154÷14)cm\Rightarrow l=11cm$

Therefore, the perimeter of rectangle = 2(length + breadth)

$\Rightarrow \text{perimeter}=2(11+14)=2\times 25=50cm$
