Question

The length of the side of a square of area $1$ square meter is $:$

• A. $20m$
• B. $40m$
• C. $10m$
• D. $1m$

Answer 1

The correct option is D

$1m$

Area of a square $=a^2$

It is given that area of a square $=1m^2$

We know that area of a square $=a^2,$where $a$ is the side of a square

$a^2=1$

$a=1m$

Hence, the side of a square is $1m,$

therefore option $\left(D\right)$ is correct.
