Which formula is used to determine the area of a rhombus?

• A. A = B × H
• B. A = 1/2 diagonal1 × diagonal2
• C. A = b × h
• D. A = Base + Height

Answer: (B)

The formula used to determine the area of a rhombus is A = 1/2 × diagonal1 × diagonal2. This formula is derived from the properties of a rhombus, which is a type of quadrilateral where all sides are of equal length and the diagonals bisect each other at right angles. In a rhombus, the diagonals create four right triangles. The area can be found by calculating the area of one of those triangles and then multiplying by four. However, using the diagonals directly simplifies the calculation. By taking half the product of the lengths of the two diagonals, you effectively get the total area of the four right triangles combined. The other options relate to different geometric figures or concepts: one mentions the area of a rectangle (A = B × H), which applies when finding the area using the base and height of a rectangle, while another incorrectly employs the same formula for the base and height of a different context. Lastly, a simple addition of base and height does not yield an area and is unrelated to calculating area for any shape. Thus, option B is the correct and specific formula for finding the area of a rhombus.
