Question 1153139: The vertices of triangle ABC are A(1,5), B(7,-1) and C(-2,-2). What is the perimeter of this triangle?
Answer by math_helper(2461) (Show Source): You can put this solution on YOUR website!
The perimeter is the sum of the lengths of each side:
AB = ... or approx 8.485
BC = ... approx 9.055
CA = ... approx 7.616
Adding the three lengths (and assuming my math is correct):
perimeter = 25.156 units
