Question: If the area of a square is 81 square meters, what is the length of one side of the square in meters?

Options:

Correct Answer: 9

Solution:

Area = side², so side = √81 = 9 meters.

If the area of a square is 81 square meters, what is the length of one side of the square in meters?

If the area of a square is 81 square meters, what is the length of one side of the square in meters?

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 81 square meters. So we can write the equation: side² = 81.
Step 3: To find the length of one side, we need to take the square root of 81. This is written as side = √81.
Step 4: Calculate the square root of 81. The square root of 81 is 9.
Step 5: Therefore, the length of one side of the square is 9 meters.

Area of a Square – The area of a square is calculated by squaring the length of one of its sides (Area = side²).
Square Root Calculation – Finding the length of a side involves taking the square root of the area.
