Question

The lengths of the two diagonals of a rhombus are 20 cm and 23 cm. What is the area (in cm?) of the rhombus?

• A. 460
• B. 345
• C. 230
• D. 115

Answer 1

Answer:

C. 230

Area of a rhombus:
$\text{Area} = \frac{1}{2} \times d_1 \times d_2$

Given:
$d_1 = 20,\quad d_2 = 23$
$\text{Area} = \frac{1}{2} \times 20 \times 23 = 10 \times 23 = 230$

Final Answer: 230 cm²
