If the measure of one side and one diagonal of a rhombus are 10 cm and 16 cm respectively, then its area (in cm²) is :
-
- 60
- 64
- 96
- 100
- 60
Correct Option: C
Using Rule 12, A
AB = 10cm,
AC = 16 cm;
⇒ AO = 8 cm
∴ BO = √10² - 8²
= √100 - 64 = √36 = 6 cm
∴ BD = 12cm
Hence,
Area of rhombus = d1d2
| = | × 16 × 12 = 96cm² | |
