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

To find the area of a rectangle, you multiply its length by its width. Given that the length is 10 cm and the width is 5 cm, the calculation would be:

Area = Length × Width

Area = 10 cm × 5 cm

Area = 50 cm²

This represents the total amount of space enclosed within the rectangle. The area of 50 cm² indicates that if you were to cover that rectangle with 1 cm² squares, you would need exactly 50 squares. Thus, the correct answer is indeed 50 cm².
