Calculate the area of the triangle shown in the diagram.

a) To find the area of the triangle, we use the formula:

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

Step 1: Identify the base and height from the diagram.
The base of the triangle is $7 \text{ cm}$.
The height of the triangle is $8 \text{ cm}$.

Step 2: Substitute the values into the formula and calculate the area.

$$\text{Area} = \frac{1}{2} \times 7 \text{ cm} \times 8 \text{ cm}$$ $$$$
