(a)2400 sq. cm
(b)2480 sq. cm
(c)2560 sq. cm
(d)Data inadequate
(e)None of these
Answer
Answer (as printed):
Explanation
Let breadth $=x \mathrm{cm}$. Then, length $=\left(\frac{160}{100} x\right) \mathrm{cm}=\frac{8}{5} x \mathrm{cm}$. So, $\frac{8}{5} x-x=24 \Leftrightarrow \frac{3}{5} x=24 \Leftrightarrow x=\left(\frac{24 \times 5}{3}\right)=40$. ∴ Length $=64 \mathrm{cm}$, Breadth $=40 \mathrm{cm}$. Area $=(64 \times 40) \mathrm{cm}^{2}=2560 \mathrm{cm}^{2}$.
