The area of the largest triangle, that can be inscribed in a semicircle of radius r cm, is
-
- 2r cm²
- r² cm²
- 2r² cm²
- 1/2 r² cm²
- 2r cm²
Correct Option: B
Using Rule 1,
The largest triangle inscribed in a semi-circle will have base equal to 2r cm and height equal to r cm as shown in figure.
| ∴ Area = | × base × height | |
| 2 |
| = | × 2r × r = r² cm² | |
| 2 |
