If the area of a rectangle is 48 square units and the width is 6 units, what is the length?

To find the length of a rectangle when given the area and the width, you can use the formula for the area of a rectangle:

Area = Length × Width.

Here, you know the area is 48 square units and the width is 6 units. You can rearrange the formula to solve for the length:

Length = Area ÷ Width.

Substituting the values you have:

Length = 48 square units ÷ 6 units.

Calculating this gives:

Length = 8 units.

Therefore, the length of the rectangle is indeed 8 units, confirming that this choice is correct. This method of dividing the area by the width is a fundamental concept when dealing with rectangles, allowing you to find one dimension when the area and the other dimension are known.
