I'll solve the problem by calculating the area of each triangle shown in the worksheet. The formula for the area of a triangle is: Area = (base × height) / 2.
Let me go through each triangle one by one:
First row:
1. Triangle 1: base = 8, height = 6 → Area = (8 × 6) / 2 = 48 / 2 = 24
2. Triangle 2: base = 5, height = 7 → Area = (5 × 7) / 2 = 35 / 2 = 17.5
3. Triangle 3: base = 9, height = 4 → Area = (9 × 4) / 2 = 36 / 2 = 18
Second row:
4. Triangle 4: base = 6, height = 8 → Area = (6 × 8) / 2 = 48 / 2 = 24
5. Triangle 5: base = 7, height = 5 → Area = (7 × 5) / 2 = 35 / 2 = 17.5
6. Triangle 6: base = 8, height = 6 → Area = (8 × 6) / 2 = 48 / 2 = 24
Third row:
7. Triangle 7: base = 10, height = 5 → Area = (10 × 5) / 2 = 50 / 2 = 25
8. Triangle 8: base = 6, height = 9 → Area = (6 × 9) / 2 = 54 / 2 = 27
9. Triangle 9: base = 7, height = 8 → Area = (7 × 8) / 2 = 56 / 2 = 28
The areas for the triangles are:
- First row: 24, 17.5, 18
- Second row: 24, 17.5, 24
- Third row: 25, 27, 28
Parent Tip: Review the logic above to help your child master the concept of triangle area and perimeter worksheet.
