Question

ABCD is a rhombus $AC=12\text{cm}$ and $BD=20\text{cm},$ then area of rhombus (in ${\text{cm}}^2$) is

• A. 240
• B. 120
• C. 60
• D. 180

Answer 1

Answer: (B)

120

The diagonals of rhombus are:

$AC=12\text{cm}$

$BD=20\text{cm}$

The area of rhombus is given by $A$, such that:

$A=\frac{1}{2}AC\times BD$ $=\frac{12\times 20}{2}=120{\text{cm}}^2$
