Cam is playing four square on the playground with her friends. The area of the four square is 169 square feet. What is the side length of each player's square?

6.5 feet

Step-by-step explanation:

If total area is 169 square feet then we need to find 1/4 of that for each individual square. Each square is 42.25 feet square which would give a side length of 6.5 on each square.

6.5×6.5=42.25 area of each square

42.25×4=169 total area of all four squares
