The perimeter of an isosceles triangle ABC with CA = CB, is 420. Find the area of this triangle if D is a point on the base of the triangle such that CD and CA are integers, and AD and DB are primes.

I'm finding it difficult to follow your posting.

There are two different values given for AD (17 and 133).

AB and DB are given to be 120 and 139 respectively when in fact AB = AD + DB.
