While trying to find a toy his brother hid, John looked over an area of 200 square feet. What is the approximate length of each side of the square area. Round your answer to the nearest foot.

First you need to list the two closest perfect squares near the number 200. That would be 14 and 15. 14 is 196 and 15 is 225, so 14 is closer. 14(196) is closest to 200 so that is the number that we will take for the answer. The length of the sides of the square is about 14 ft.
