Explanation:

1)

Step1: Identify base and height

Base \( b = 3.2\) m, Height \( h = 4.5\) m

Step2: Apply triangle area formula

Area \( = \frac{1}{2} \times b \times h = \frac{1}{2} \times 3.2 \times 4.5 \)
\( = 1.6 \times 4.5 = 7.2 \) m²

2)

Step1: Identify base and height

Base \( b = 2.2\) ft, Height \( h = 3.5\) ft

Step2: Apply triangle area formula

Area \( = \frac{1}{2} \times 2.2 \times 3.5 \)
\( = 1.1 \times 3.5 = 3.85 \) ft²

3)

Step1: Identify base and height

Base \( b = 6.9\) yd, Height \( h = 3.2\) yd

Step2: Apply triangle area formula

Area \( = \frac{1}{2} \times 6.9 \times 3.2 \)
\( = 3.45 \times 3.2 = 11.04 \) yd²

4)

Answer:

s:

1. \( 7.2 \) m²
2. \( 3.85 \) ft²
3. \( 11.04 \) yd²
4. \( 11.13 \) ft²
5. \( 16.65 \) yd²
6. \( 8.5 \) m²
7. \( 17.42 \) yd²
8. \( 21.07 \) in²
9. \( 71.98 \) ft²
