 | ||
| 
 | ||
| ## Description
 | ||
| <section id='description'>
 | ||
| Let us define a geometric triangle as an integer sided triangle with sides a ≤ b ≤ c so that its sides form a geometric progression, i.e. b2 = a · c . 
 | ||
| 
 | ||
| An example of such a geometric triangle is the triangle with sides a = 144, b = 156 and c = 169.
 | ||
| 
 | ||
| There are 861805 geometric triangles with perimeter ≤ 106 .
 | ||
| 
 | ||
| How many geometric triangles exist with perimeter ≤ 2.5·1013 ?
