What is the area of a rectangle that is 6 cm wide and 9 cm long?

To find the area of a rectangle, you multiply its width by its length. In this case, the width is 6 cm and the length is 9 cm. Performing the calculation:

Area = Width × Length Area = 6 cm × 9 cm Area = 54 cm²

Thus, the area of the rectangle is 54 cm², making the most accurate choice the first option. Option B, which states an area of 45 cm², does not reflect the correct multiplication of the given dimensions.
