Calculation of the Rectangle's Area

To find the area of a rectangle, we can use the formula: Area = length * width.

In this case, the length of one side of the rectangle is given as 12 cm. Since a rectangle has two pairs of equal sides, we can assume that the other side also measures 12 cm.

Therefore, the area of the rectangle can be calculated as follows:

Area = length * width = 12 cm * 12 cm = 144 cm².

So, the area of the rectangle is 144 square centimeters.
