Question

The area of a rectangular plot is 462 m² and its length is 28 m. Find the perimeter of the plot.

Answer 1

Area of the rectangular plot = 462 m²
Length (l) = 28 m
$$\begin{gathered} \mathrm{Area}\mathrm{of}\mathrm{a}\mathrm{rectangle}=\mathrm{Length}\left(l\right)\mathrm{x}\mathrm{Breadth}\left(b\right) \\ \Rightarrow 462=28\mathrm{x}b \\ \Rightarrow b=16.5\mathrm{m} \end{gathered}$$

Perimeter of the plot = $2\left(l+b\right)$
$$\begin{gathered} =2\left(28+16.5\right) \\ =2\times 44.5 \\ =89\mathrm{m} \end{gathered}$$
