Problem |
Calculate the area of a rhombus having diagonals equal to 9 cm and 6 cm. |
|
2 |
Step |
Given diagonals are |
p = 9 cm ,q = 6 cm |
3 |
Formula |
The area of a Rhombus formula is A = \$ (p \times q)/2\$. |
|
4 |
Step |
Substitute the values into the formula |
\$(9 \times 6)/2\$ \$27 cm^2\$ |
5 |
Solution |
So, the area of a rhombus is \$ 27 cm^2\$. |

7 |
Choice-A |
This option uses square meters (m²) as the unit. Since the diagonals are given in centimeters (cm), the area must be in square centimeters (cm²). This option is incorrect because the unit |
Wrong \$27 m^2\$ |
8 |
Choice-B |
This is just a wrong calculation. It’s not related to the actual area of the rhombus |
Wrong \$25 cm^2\$ |
9 |
Choice-C |
This is incorrect because the calculated area is \$27 cm^2\$, not \$24 cm^2\$ |
Wrong \$24 cm^2\$ |
10 |
Choice-D |
This is the correct answer. The calculation \$(1/2 \times 9 cm \times 6 cm)\$ gives you 27 cm². The units are also correct |
Correct \$27 cm^2\$ |
