Work Step by Step
The area of a square is the length of a side squared. Thus, this problem requires the exact same process as 19 through 23 where we approximate the root of the area, so we consider the closest square root that gives us an integer answer. We know that the square root of 3025 is 55. The square root of 3000 is fairly close to the square root of 3025, so 55 is a good approximation for the square root of 3000. Thus, each side of the launching pad is about 55 feet long.
