What is the result of multiplying the area of a rectangle with length 5 and width 3?

To find the area of a rectangle, the formula used is:

Area = length × width

In this case, the length of the rectangle is 5 units, and the width is 3 units. Applying the formula:

Area = 5 × 3 = 15 square units.

This calculation confirms that the area of the rectangle is indeed 15. Thus, the correct answer reflects the outcome of multiplying the length and width together to arrive at the area, reinforcing the concept of how to compute the area of rectangular shapes effectively. Understanding this formula is essential for solving problems related to area in geometry.
