Question

Accepted Answer

# Explanation:
## Step1: Recall the area formula for a square
The area formula for 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 $s = 1.2$ feet. Then $A=(1.2)^2$.
$$
\begin{align*}
(1.2)^2&=(1 + 0.2)^2\
&=1^2+2\times1\times0.2 + 0.2^2\
&=1 + 0.4+0.04\
&=1.44
\end{align*}
$$

# Answer:
The area of the square is $1.44$ square feet.
