Question

Two adjacent sides of a parallelogram are 4 cm and 3 cm respectively. Find its perimeter.

Answer 1

$$\begin{gathered} \mathrm{We}\mathrm{know}\mathrm{that}\mathrm{the}\mathrm{opposite}\mathrm{sides}\mathrm{of}\mathrm{a}\mathrm{parallelogram}\mathrm{are}\mathrm{equal}. \\ \mathrm{Two}\mathrm{sides}\mathrm{are}\mathrm{given},\mathrm{i}.\mathrm{e}.4\mathrm{cm}\mathrm{and}3\mathrm{cm}. \\ \mathrm{Therefore},\mathrm{the}\mathrm{rest}\mathrm{of}\mathrm{the}\mathrm{sies}\mathrm{will}\mathrm{also}\mathrm{be}4\mathrm{cm}\mathrm{and}3\mathrm{cm}. \\ \therefore P\mathrm{erimeter}=S\mathrm{um}\mathrm{of}\mathrm{all}the\mathrm{sides}\mathrm{of}a\mathrm{parallelogram} \\ =4+3+4+3 \\ =14\mathrm{cm} \end{gathered}$$
