What is the area of a rectangle with length 8 and width 5?

To find the area of a rectangle, the formula used is the product of its length and width. In this case, the rectangle has a length of 8 and a width of 5. By multiplying these two dimensions together:

Area = Length × Width = 8 × 5 = 40.

This calculation shows that the area of the rectangle is indeed 40 square units. Understanding this formula is key for solving any problem related to the area of rectangles, as it directly correlates the size of the shape to its dimensions.
