Question

A piece of copper wire is bent into the shape of a square which encloses an area of $2116$ sq cm. Find the length of the copper wire.

Answer 1

When copper wire is bent in the form of a square.

Area of figure enclosed (square) $={\left(side\right)}^2$

Given:-

Area of figure enclosed (square) $=2116{cm}^2$

$\therefore {\left(side\right)}^2=2116$

$\Rightarrow side=\sqrt{2116}=46cm$

As we know that all sides of a square are equal.

$\therefore$ length of copper wire $=46\times 4=184cm$

Hence, the length of the copper wire is 184 cm.
