What is the area of a rectangle with a length of 8 cm and a width of 3 cm?

24 cm²
30 cm²
20 cm²
32 cm²

The correct answer is: 24 cm²

To find the area of a rectangle, you multiply the length by the width. In this case, the length is 8 cm and the width is 3 cm. The calculation for the area is: Area = Length × Width Area = 8 cm × 3 cm Area = 24 cm² Thus, the area of the rectangle is 24 square centimeters, making this the correct answer. This formula holds true regardless of the specific measurements, as it is a fundamental characteristic of rectangles. Understanding this can help you apply the same principle to find the area of other rectangles with different dimensions.
