Step-by-step explanation:

Do 72 divided by 4 because it is a square so all sides are equal

Hiya! ✌.ʕʘ‿ʘʔ.✌

Okay, so with a square, ALL sides are EQUAL.

To find the perimeter of a shape, you just need to add the measure of all sides together.

What you can do, is since all sides are equal, and a square has four sides, just get the measure of ONE side and multiply that by 4! (ﾉ◕ヮ◕)ﾉ*:･ﾟ✧

The perimeter is 72 meters and if we find the value of u, we get the value of all sides.

Let's set this up as an equation:

P = 4u where P = perimeter and u = measure of one side

Let's insert the given value (72) into the equation for perimeter

72 = 4u

Now we have to solve for u, and to do that, we have to get it by itself on that side of the equation. u is being multiplied by 4, so do the opposite by dividing both sides of the equation by 4!

72/4=18

4u/4=u

Now our equation looks like this:

18 = u

So the value of u is 18! (✿◠‿◠)

To prove it, insert it into the formula... P = 4(18)... P = 72.

Boom! :D
