To find the area of a triangle, we use this simple formula:
Area = (base × height) ÷ 2
We’ll go through each triangle one by one.
---
Triangle 1:
- Base = 10
- Height = 14
→ Area = (10 × 14) ÷ 2 = 140 ÷ 2 =
70
---
Triangle 2:
- Base = 5
- Height = 9
→ Area = (5 × 9) ÷ 2 = 45 ÷ 2 =
22.5
---
Triangle 3:
- Base = 6
- Height = 6
→ Area = (6 × 6) ÷ 2 = 36 ÷ 2 =
18
---
Triangle 4:
- Base = 2
- Height = 8
→ Area = (2 × 8) ÷ 2 = 16 ÷ 2 =
8
---
Triangle 5:
- Base = 5
- Height = 12
→ Area = (5 × 12) ÷ 2 = 60 ÷ 2 =
30
---
Triangle 6:
- Base = 7
- Height = 3
→ Area = (7 × 3) ÷ 2 = 21 ÷ 2 =
10.5
---
All calculations checked and verified.
Final Answer:
70, 22.5, 18, 8, 30, 10.5
