The length of one side of the rectangle is 8 cm, and it is 3 cm longer than the other side.

The length of one side of the rectangle is 8 cm, and it is 3 cm longer than the other side. What is the area of the rectangle?

The area of the rectangle is calculated by the formula:

S = a * b.

Let’s find this value, for such a figure, the length of which is 8 cm, and the width is 3 cm less, by writing the expression:

S = 8 * (8 – 3). proceeding in the order of performing mathematical operations, first of all, we find the value in parentheses, then we perform the multiplication:

S = 8 * 5 = 40 cm².
