Question

Dexter has to divide his rectangular field into two parts from one corner to the other using fence. If the area of the field is $540$ $m^2$ and the length of the field is $36$ $m$, then what will be the length of the fence needed?

Answer 1

Area of a rectangle $=$ length $\times$ breadth

Since the area of the field is $540m^2$, and its length is $36m$, the breadth would be $\frac{540}{36}=15m$

Te length of the required fence is the length of the diagonal.

It can be found out using, $\sqrt{(15{)}^2+(36{)}^2}=\sqrt{225+1296}=\sqrt{1521}=39m$
