Calculate Square Root: Finding Side Length When Area = 100

How long are the sides of a square if its area is equal to 100?

To determine the length of the sides of a square when the area is given, we proceed as follows:

• Step 1: Recall the formula for the area of a square: $\text{Area} = \text{side}^2$.
• Step 2: We need to find the side length, so we rearrange the formula to solve for the side: $\text{side} = \sqrt{\text{Area}}$.
• Step 3: Substitute the given area into the formula: $\text{side} = \sqrt{100}$.
• Step 4: Calculate the square root: $\sqrt{100} = 10$.

Therefore, the length of each side of the square is $10$.
