# --description--
考虑具有基本长度b = 16和腿L = 17的等腰三角形。
通过使用毕达哥拉斯定理可以看出三角形的高度h =√172-82= 15比基本长度小1。当b = 272且L = 305时我们得到h = 273这比基本长度多一个这是第二个最小的等腰三角形具有h = b±1的性质。找到12个最小等腰的ΣL h = b±1且bL为正整数的三角形。
# --hints--
`euler138()`应该返回1118049290473932。
```js
assert.strictEqual(euler138(), 1118049290473932);
```
# --seed--
## --seed-contents--

}
euler138();
```
