Part (a)

Step 1: From the figure, the length of base AB = 8 cm.

Step 2: The perpendicular height $h$ from C to AB = 4 cm.

Step 3: Formula for area of triangle:

$$\text{Area of } \triangle ABC = \frac{1}{2} \times \text{base} \times \text{height}$$

Step 4: Substitute the values:

$$\text{Area of } \triangle ABC = \frac{1}{2} \times 8\ \text{cm} \times 4\ \text{cm}$$

Step 5: Simplify:

$$\text{Area of } \triangle ABC = 16\ \text{cm}^2$$

16 cm^2

Part (b)

Step 1: From the figure, the length of base AB = 8 cm.

Step 2: The perpendicular height $h$ from C to AB = 6 cm.

Step 3: Formula for area of triangle:
