12. If a rectangle has a length of 8 meters and a width of 5 meters, what is the area of the rectangle?
To find the area of a rectangle, you need to multiply its length by its width.
In this case, the length of the rectangle is 8 meters and the width is 5 meters.
To get the area, you can simply multiply the length (8 meters) by the width (5 meters):
Area = Length * Width
Area = 8 meters * 5 meters
Area = 40 square meters
Therefore, the area of the rectangle is 40 square meters.
