Question

Find the length of the rectangular field if its perimeter is $240m$ and breadth is $52m$

Answer 1

Finding the length of the rectangular field:

Given perimeter of the field is $240m$ and the breadth is $52m$

perimeter of the rectangle=$2(l+b)$

$$\begin{gathered} 2(l+b)=\mathrm{perimeter} \\ 2(\mathrm{l}+52)=240 \\ \mathrm{l}+52=\frac{240}{2} \\ \mathrm{l}+52=120 \\ \mathrm{l}=120-52 \\ \mathrm{l}=68\mathrm{m} \\ \therefore \mathrm{Length}\mathrm{of}\mathrm{the}\mathrm{rectangular}\mathrm{filed}\mathrm{is}68\mathrm{m} \end{gathered}$$
