Answer :-
1.
- a = 11
- b = 13
- c = 8
S = a + b + c/2
→ 11 + 13 + 8 /2
→ 32/2
→ 16
Area of the traingle :
√ s (s - a) (s - b) (s - c)
→ √ 16 (16 - 11) (16 - 13) (16 - 8)
→ √ 16 × 5 × 3 × 8
→ √1920
→ √ 43.8 cm²
2.
- a = 120
- b = 80
- c = 50
S = a + b + c/2
→ 120 + 80 + 50 /2
→ 250/2
→ 125
Area of the triangle :
√ s (s - a) (s - b) (s - c)
→ √ 125 (125 - 120) (125 - 80) (125 - 50)
→ √ 125 × 5 × 45 × 75
→ √ 2109375
→ 1452.36 cm²
