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:

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

Step 4: Substitute the values:

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

Step 5: Simplify:

$Area of \triangle ABC = 16\ cm^2$

16 \text{ 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:
