Question

The diagonal of a square is $15$m;find the length of its one side and perimeter.

Answer 1

Given , the diagonal of a square $=15cm$

$\because$Length of diagonal of a square $=side\sqrt{2}$

$\Rightarrow side=\frac{15}{\sqrt{2}}$

Perimeter

$=4\times side=4\left(\frac{15}{\sqrt{2}}\right)=30\sqrt{2}$

Hence, side and perimeter of square are $\frac{15}{\sqrt{2}}\text{and}30\sqrt{2}$ respectively.
