What is the area of a rectangle with a length of 8 and a width of 5?

To find the area of a rectangle, you use the formula:

Area = Length × Width.

In this case, the length of the rectangle is 8 units and the width is 5 units. By substituting these values into the formula, we have:

Area = 8 × 5 = 40 square units.

This calculation shows that the area of the rectangle is indeed 40. Understanding the area formula and how to apply it correctly to the given dimensions solidifies the concept of calculating area in geometry. This is why the answer is correct.
