Which formula gives the area of a parallelogram with base b and height h?

• A. a = l × w
• B. a = 1/2 bh
• C. a = b h
• D. p = 2(a + b)

Answer: (C)

The area of a parallelogram is found by multiplying the base by the height—the height is the perpendicular distance between the base and the opposite side. So the area is a = b × h. This matches the formula a = b h. For example, if the base is 8 units and the height is 3 units, the area is 24 square units. The other formulas correspond to different shapes or measures: a = l × w is for rectangles, a = 1/2 bh is for triangles, and p = 2(a + b) is a perimeter formula.
