Question

If the area of square is numerically equal to its perimeter,then the length of each side is

• A. $1unit$
• B. $2units$
• C. $3units$
• D. $4units$

Answer 1

The correct option is D

$4units$

Let the length of each side is $xunits$.

A/q , Area of square = perimeter of square

$$\begin{gathered} \Rightarrow {\left(side\right)}^2=4\times side \\ \Rightarrow {\left(x\right)}^2=4\times x \\ \Rightarrow x=4 \end{gathered}$$

Hence (d) is the correct option
