In Figure, `M ,N` and `P` are the mid-points of `A B ,A C` and `B C` respectively. If `M N=3c m ,N P=3. 5c m` and `M P=2. 5c m ,` calculate `B C ,A B` and `A Cdot`

Explanation

To solve the problem step by step, we will use the properties of midpoints in a triangle. Let's denote the lengths as follows:

- \( M \) is the midpoint of \( AB \)
- \( N \) is the midpoint of \( AC \)
- \( P \) is the midpoint of \( BC \)

Given:
- \( MN = 3 \, \text{cm} \)
