Question

Accepted Answer

# Explanation:
## Step1: Recall the formula for the area of a square
The area formula of a square is $A = s^2$, where $s$ is the side - length of the square.
## Step2: Substitute the given side - length into the formula
Given $s = 2.1$ meters. Then $A=(2.1)^2$.
$$
\begin{align*}
(2.1)^2&=(2 + 0.1)^2\
&=2^2+2\times2\times0.1+0.1^2\
&=4 + 0.4+0.01\
&=4.41
\end{align*}
$$

# Answer:
$4.41$ square meters
