Answer:
18.75 inches
Explanation:
First, you must know that the perimeter of a shape is the sum of all the sides added together. Since we're dealing with a square, we have four sides.
Next, you need to know that squares also have four equal sides. By knowing this information, we can easily infer that the solution is found by dividing 75 by 4. Once you do this, you will get a final answer of 18.75 inches per side.
75 / 4 = 18.75
