Two circles of radil `5c m` and `3c m` intersect at two points and the distance between their centres is `4c mdot` Find the length of the common chord.

Explanation

To find the length of the common chord of two intersecting circles with given radii and distance between their centers, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Given Values:**
- Radius of the first circle (R1) = 5 cm
- Radius of the second circle (R2) = 3 cm
- Distance between the centers (d) = 4 cm
