The two opposite sides of the rectangle have a total length of 12 cm. What is the area of the rectangle if the third side is 12 cm.

About the rectangle, we know that:

1. A rectangle is a parallelogram.
2. Opposite sides are equal.
3. Opposite sides are parallel.
4. Adjacent sides are perpendicular to each other.
In order to find the area of ​​a rectangle, you need to multiply its width by its length. In the form of a formula, this can be represented as S = h * b, where S is the area, h is the height, b is the width.

Let one side of the rectangle be denoted by x, then its opposite side will also be x. By condition, they have a total length of 12 cm. 2x = 12; x = 6.

Let it be high.

The third side in this case will be 12 cm wide.

From the formula S = h * b we have S = 12 * 6 = 72 cm2.

Answer: 72 cm 2.
