(a)24 cm
(b)26 cm
(c)28 cm
(d)Cannot be determined None of these
Answer
Answer (as printed): C
Explanation
Area of circle $=\left(\frac{22}{7} \times 14 \times 14\right) \mathrm{cm}^{2}=616 \mathrm{cm}^{2}$. Let the length of the rectangle be $l \mathrm{cm}$. Then, $22 l=616 \Rightarrow l=\frac{616}{22}=28 \mathrm{cm}$.
