New question: Given that the length of AM is √45, find the area of triangle ANC
-Points: A: (-9, -1) M: (-3, 2) C: (3, 5) N: (-4, 4)
Area of triangle formula: A= 1/2(√45x2)x√5

I just don't understand where the √5 comes from at the end of the triangle formula. If you could help me out, that would be amazing! (My test is this Monday) Thanks!
