If a rectangle has a length of 10 units and a width of 5 units, what is its area?

To determine the area of a rectangle, you multiply its length by its width. In this case, the given length is 10 units and the width is 5 units. By performing the calculation:

Area = Length × Width Area = 10 units × 5 units Area = 50 square units

Thus, the area of the rectangle is 50 square units. This option correctly reflects the application of the area formula for a rectangle, ensuring clarity on how to derive the area using the known dimensions. Other choices do not align with the correct formula or the mathematics applied to this scenario.
