Find the area of a triangle whose perimeter is 22 cm, one side is 9 cm and the difference of other two sides is 3 cm.

Answer

To find the area of the triangle with the given conditions, we can follow these steps:

### Step 1: Define the sides of the triangle
Let the sides of the triangle be \( A \), \( B \), and \( C \). We know that:
- The perimeter \( P = A + B + C = 22 \) cm
- One side \( A = 9 \) cm
- The difference of the other two sides \( |B - C| = 3 \) cm
