Brody calculated the area of a square to be \( \frac{16}{36} \) square loo Which shows the side length of the square?

Brody's calculation indicates that the area of the square is \( \frac{16}{36} \), which simplifies to \( \frac{4}{9} \). To find the side length, we take the square root of the area. Therefore, the side length is \( \sqrt{\frac{4}{9}} = \frac{2}{3} \) loo. Now, if Brody had wanted to check his work, he could have calculated the side length first and squared it to see if it indeed equaled the area he calculated. A common mistake is forgetting that the area is always in square units, so when moving from area back to side length, square roots must be taken carefully!
