In the given figure which is a square, the length of its side is 7 meters long.

The 7 meters here is the value of s.

To get the area, the formula is:


A=s^2

To get the area, we replace "s" with "7 meters" in the formula above.


A=(7meters)^2

Then, we apply the exponent.


\begin{gathered} A=7meters*7meters \\ A=49square\text{ }meters \end{gathered}

Therefore, the area of the square is 49 square meters.

To get the perimeter of the square, we use the formula P = 4s.

Perimeter is the total distance around the square.

Let's replace the "s" in the formula with "7 meters". Then, solve.


\begin{gathered} P=4*7meters \\ P=28\text{ }meters \end{gathered}

Therefore, the distance around the square or its perimeter is 28 meters.
