Determine the area of a square abcd with AB=3cm
To determine the area of a square, we need to know the length of one side. In this case, you have mentioned that AB is 3 cm, which is the length of one side of the square.
To find the area of a square, we can use the formula:
Area = Side length * Side length
In this case, the side length is 3 cm.
Area = 3 cm * 3 cm = 9 cm^2
Therefore, the area of the square ABCD is 9 square centimeters.
