`DeltaABC` is isosceles with `AB=AC=7.5cm and BC=9cm.` The height `AD` from `A` to `BC` is `6cm.` Find the area of `DeltaABC.` What will be the height from `C` to `AB , CE`

Explanation

To solve the problem step by step, we will first find the area of triangle ABC and then calculate the height from point C to line AB.

### Step 1: Calculate the Area of Triangle ABC
1. **Identify the base and height**: In triangle ABC, we can take BC as the base, which is 9 cm, and the height AD from point A to line BC, which is given as 6 cm.
2. **Use the area formula**: The area \( A \) of a triangle can be calculated using the formula:
\[ A = \frac{1}{2} \times \text{base} \times \text{height} \]
