If a rectangle has a length of 10 and a width of 5, 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, and the width is given as 5. Plugging these values into the formula gives:

Area = 10 × 5 = 50.

Thus, the area is 50 square units.

This result aligns with option C, which is the correct answer. Other options do not accurately represent the calculated area based on the dimensions provided.
