Answer 1

Answer:

Equation: $36=4s$

Solution: $s=9$

Step-by-step explanation:

A square is a quadrilateral that has four equal sides and four equal angles that measure 90 degrees (An angle that measures 90 degrees is also known as "Right triangle".

By definition, the perimeter of a square can be calculated by multiplying the length of any of its sides by 4 (because all its sides are congruent, as it was explained before).

In this case, you know that the perimeter of this square is 36 feet.

 Then, you can write the following equation to model this situation:

$36=4s$

Where "s" is the length of any side of the square.

Then, you need to solve for "s" in order to find its value. Divide both sides of the equation by 4.

You get that it is:

$\frac{36}{4}=\frac{4s}{4}\\\\s=9$
