What is the expression for the area of a rectangle with length 5 and width 3?

To find the area of a rectangle, you use the formula: Area = Length × Width. In this case, the length of the rectangle is given as 5 units and the width as 3 units.

By substituting the values into the formula, we calculate:

Area = 5 × 3 = 15.

Therefore, the expression for the area of the rectangle results in 15 square units. This aligns perfectly with the information given in the question, confirming that the area has been accurately calculated.
