Find a Pythagorean triplet (a, b,c) such that a < b < c and (b+c) = a*a, a>7

To find a Pythagorean triplet \((a, b, c)\) such that \( a < b < c \), \( b + c = a^2 \), and \( a > 7 \), let’s go through a systematic approach.

Given:
- \(a^2 = b + c\)
- \(a^2 = b^2 + c^2\)

To simplify, let’s express \(c\) in terms of \(a\) and \(b\) and verify if there are integers that satisfy all conditions.

### Solution
Let's start by trying values of \(a > 7\) and testing if \( b + c = a^2 \) holds when \((a, b, c)\) are integers.

1. **For \(a = 8\):**
   \[
   a^2 = 8^2 = 64
   \]
   Now we want integers \(b\) and \(c\) such that:
   - \( b + c = 64 \)
   - \( a < b < c \)
   - \( b^2 + c^2 = a^2 = 64 \)

2. **Check possible values:**  
This requires systematic testing or a general method for generating Pythagorean triplets under these conditions. After testing values, we can confirm the solution.
