According to the rules of triangle inequality, the sum of any two sides of a triangle MUST ALWAYS EXCEED the value of the third side. But here, it is observed that 7+5 =12. This should not happen.
Therefore, we can conclude that it's impossible for a triangle to measure 5, 7 and 12

No. In a triangle, any 2 sides MUST be greater than the remaining side. In this case, 5 + 7 !> 12.
