To solve this worksheet, we need to calculate the
area of each triangle using the formula:
$$
\text{Area} = \frac{1}{2} \times \text{base} \times \text{height}
$$
We'll go through each triangle one by one.
---
🔹 Triangle 1:
- Base = 10
- Height = 14
$$
\text{Area} = \frac{1}{2} \times 10 \times 14 = 5 \times 14 = 70
$$
✔ Area = 70
---
🔹 Triangle 2:
- Base = 5
- Height = 9
$$
\text{Area} = \frac{1}{2} \times 5 \times 9 = 2.5 \times 9 = 22.5
$$
✔ Area = 22.5
---
🔹 Triangle 3:
- Base = 6
- Height = 6
$$
\text{Area} = \frac{1}{2} \times 6 \times 6 = 3 \times 6 = 18
$$
✔ Area = 18
---
🔹 Triangle 4:
- Base = 2
- Height = 8
$$
\text{Area} = \frac{1}{2} \times 2 \times 8 = 1 \times 8 = 8
$$
✔ Area = 8
---
🔹 Triangle 5:
- Base = 5
- Height = 12
$$
\text{Area} = \frac{1}{2} \times 5 \times 12 = 2.5 \times 12 = 30
$$
✔ Area = 30
---
🔹 Triangle 6:
- Base = 7
- Height = 3
$$
\text{Area} = \frac{1}{2} \times 7 \times 3 = 3.5 \times 3 = 10.5
$$
✔ Area = 10.5
