What expression represents the area of a rectangle with lengths of 5 and 10?

  1. 15

  2. 50

  3. 8

  4. 25

The correct answer is: 50

The area of a rectangle is calculated using the formula: Area = length × width. In this case, the given lengths are 5 and 10. Substituting these values into the formula yields: Area = 5 × 10 = 50. This calculation clearly shows that the correct representation of the area of the rectangle is 50 square units. Understanding this formula is fundamental in geometry and helps in solving many real-world problems involving rectangles.
