Which formula represents the area of a parallelogram?

The area of a parallelogram is represented by the formula A = bh, where "A" stands for area, "b" is the length of the base, and "h" is the height. This formula is derived from the concept that the area can be calculated by multiplying the base of the parallelogram by its height. The height is the perpendicular distance from the base to the opposite side, ensuring that the area reflects the true extent of the shape.

This formula is specifically tailored for parallelograms, as it accounts for their unique properties of having parallel opposite sides. Other formulas listed correspond to different shapes or interpretations: for example, A = lw refers to the area of a rectangle, A = (1/2)bh is used for triangles, and A = 2l + 2w calculates the perimeter rather than the area. Understanding the distinct properties and definitions of these shapes is critical in applying the correct formula for area calculation.
