What is the area of a rectangle with length 9 and width 6?

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

Area = Length × Width = 9 × 6 = 54.

Thus, the area of the rectangle is 54 square units. This calculation aligns with the properties of rectangles where the area can be determined straightforwardly through this multiplication method.
