If the area of a rectangle is 24 square units and one side is 4 units, what is the length of the other side?

  1. 4 units

  2. 6 units

  3. 8 units

  4. 10 units

The correct answer is: 6 units

To find the length of the other side of a rectangle when the area and one side length are known, we can use the formula for the area of a rectangle, which is: Area = length × width In this case, we know the area is 24 square units and one side (let's say the width) is 4 units. To find the length, we can rearrange the formula: length = Area / width Substituting the known values: length = 24 square units / 4 units Calculating this gives: length = 6 units Thus, the length of the other side is 6 units. This is confirmed by the calculations and the context of the question, showing that the dimensions of the rectangle multiply to give the specified area of 24 square units.
