What is the rhombus area formula according to the given material?

• A. A = a^2
• B. A = ah/2
• C. A = h/a
• D. A = ah

Answer: (D)

Area of a rhombus (like any parallelogram) is found by multiplying the base by the perpendicular height. In this material, the base is labeled a and the height is labeled h, so the area is A = a × h. The other expressions don’t fit this shape: a^2 would be the area of a square with side a, ah/2 is the formula for a triangle’s area, and h/a isn’t a standard area expression. So the proper formula for this rhombus is A = a h.
