How do you calculate the area of a rectangle?

Add the length and width together
Multiply the length by the width
Divide the length by the width
Subtract the width from the length

The correct answer is: Multiply the length by the width

To calculate the area of a rectangle, you use the formula that involves multiplying the length by the width. This formula works because the area is a measure of how much space is contained within the boundary of the rectangle. By multiplying the length (the longer side) by the width (the shorter side), you effectively count the number of square units that fit inside the rectangle. This method captures the full dimension of the rectangle, providing an accurate measure of the total area. Each unit of length along one side can be matched with each unit of width along the other side, resulting in a grid of squares that represents the area. This is why the other options do not yield the correct area: simply adding, dividing, or subtracting the dimensions does not provide a measurement of space within the rectangle, which is the central concept behind area calculation.
