Question

A rectangular sheet of paper is 25 / 2 cm long and 32 / 3 cm wide. Find its
1. Perimeter
2.Area

Answer 1

Dear Student,
$$\begin{gathered} \mathrm{Length},\mathrm{l}=\frac{25}{2}\mathrm{cm} \\ \mathrm{Width},\mathrm{b}=\frac{32}{3}\mathrm{cm} \\ \mathrm{i})\mathrm{Perimeter}=2(\mathrm{l}+\mathrm{b})=2(\frac{25}{2}+\frac{32}{3})=2(\frac{75+64}{6}) \\ \Rightarrow \mathrm{Perimeter}=\frac{139}{3}\mathrm{cm} \\ \mathrm{ii})\mathrm{Area}=\mathrm{l}\times \mathrm{b}=\frac{25}{2}\times \frac{32}{3}=25\times \frac{16}{3} \\ \Rightarrow \mathrm{Area}=\frac{400}{3}{\mathrm{cm}}^2 \end{gathered}$$
