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

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

Area = Length × Width

In this case, the length of the rectangle is given as 10 units and the width is 5 units. Substituting these values into the formula:

Area = 10 units × 5 units = 50 square units

Calculating this, you multiply the two dimensions together. Since area is a measure of the two-dimensional space within the boundaries of a shape, the result is stated in square units. Thus, the area of the rectangle is 50 square units, confirming that the answer is indeed correct.

The other options reflect different calculations that do not correspond to the actual area of the rectangle based on the provided dimensions.
