The number is already in prime factored form. The prime factors are 2, 3, 5, and 7. If we multiply everything out then we end up with 2100
Area of a triangle = 1/2(B*H)
B = Base
Height = H
So if the height was 5 and the base was 10, it would be half of 50 which is 25.
It means that the distance is getting shorter from the starting point. ie. truing around
