What is the area of a rectangle that is 7 units long and 6 units wide?

To find the area of a rectangle, you can use the formula:

Area = length × width.

In this case, the rectangle has a length of 7 units and a width of 6 units. By substituting these values into the formula:

Area = 7 units × 6 units = 42 square units.

Thus, the area of the rectangle is 42 square units. This calculation shows the correct understanding of the area concept for rectangles, where you simply multiply the length by the width.
