If the area of a square is 64 cm², what is the length of one side? (2022)

If the area of a square is 64 cm², what is the length of one side? (2022)

Step 1: Understand that the area of a square is calculated by multiplying the length of one side by itself. This is written as Area = side × side or Area = side².
Step 2: We know the area of the square is 64 cm². So we can write the equation: side² = 64.
Step 3: To find the length of one side, we need to take the square root of 64. This is written as side = √64.
Step 4: Calculate the square root of 64. The square root of 64 is 8.
Step 5: Therefore, the length of one side of the square is 8 cm.

Area of a Square – The area of a square is calculated by squaring the length of one of its sides.
Square Root Calculation – Finding the length of a side involves taking the square root of the area.
