Which formula is used to find the area of a rectangle?

The area of a rectangle is determined by the product of its length and its width. This relationship arises from the definition of area, which quantifies how many square units can fill the two-dimensional space inside the shape. When you multiply the length (how long the rectangle is) by the width (how wide the rectangle is), you essentially calculate the total number of square units that fit within the boundaries of the rectangle.

Using this formula allows you to find the area easily, regardless of the specific measurements, as long as you know the length and width. For instance, if a rectangle is 5 units long and 3 units wide, using the area formula of length times width gives you 5 x 3 = 15 square units of area.

Other options provided do not represent the formula for calculating the area of a rectangle. Adding the length and width does not account for the product needed for area. The expression for base times height divided by 2 is used to find the area of a triangle, not a rectangle. Lastly, using length squared suggests calculating the area of a square, where both sides are equal, but it does not apply to rectangles unless one side is also the width. Thus, knowing that the area is found by multiplying the
