Question

The area of a rectangle is 96 $c{m}^2$. If the breadth of the rectangle is 8 cm then what is its perimeter?

• A. 40 cm
• B. 50 cm
• C. 60 cm
• D. 80 cm

Answer 1

The correct option is A 40 cm

We have, area of rectangle = 96 $c{m}^2$ and breadth = 8 cm
We know,
Area of a rectangle = length x breadth
$\Rightarrow$ length x breadth = 96 $c{m}^2$
$\Rightarrow$ length = $\frac{96}{8}$ = 12 cm
And we know, perimeter of a rectangle = 2 (length + breadth)
= 2 (12 + 8)
= 2 x 20
= 40 cm
