Question

The diagonals of a rhombus are of lengths 10 cm and 18.2 cm. What will be area ?

• A. 42 $c{m}^2$
• B. 41 $c{m}^2$
• C. 40 $c{m}^2$
• D. None of these

Answer 1

Answer: (B)

41 $c{m}^2$

Area of the rhombus = $\frac{1}{2}{d}_1,d_2$ where $d_1,d_2$ are lengths of diagonals
= $\frac{1}{2}\times 10\times 8.2c{m}^2$
= 41 $c{m}^2$
