If "s" represents the length of one side of the square and "A" represents the area, then this is a simple substitution problem.

Assuming the garden plot is a 'true' square, then all the sides, s, are equal.

Using the equation: **s = ****√A**

** **Substitute 75 square feet in for A:** s = √(75 ft**^{2}**) = 8.7 ft (Rounded to the nearest tenth)**

**Answer: Each side of Reed's garden is approximately 8.7 feet.**

Hope this helped!
