Question

If the area of the rectangle is 1/6th of the area of the circle such that area of the circle is $36c{m}^2$ and breadth of the rectangle is 6cm, then the length of the rectangle will be ___.

• A. 6 cm
• B. 12 cm
• C. 36 cm
• D. 26 cm

Answer 1

The correct option is B

12 cm

Area of rectangle = $\frac{\text{Area of circle}}{6}$
= $\frac{36}{6}$ = $6c{m}^2$
Area of reactangle = $length\times breadth$ = $6c{m}^2$
$\Rightarrow$ $length\times 1=6$

So, length = $6cm$
