Hello, I need help applying this formula I’ll add 2 photos

Answer 1

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.

$\begin{gathered} A=7meters\times7meters \\ A=49square\text{ }meters \end{gathered}$

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.

$\begin{gathered} P=4\times7meters \\ P=28\text{ }meters \end{gathered}$

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