In triangle ABC, side AB is exactly 27cm, it is 3 times larger than side BC. Find the length of the AC side if the perimeter of the ABC triangle is 61 cm.
because AB is three times more than BC, then BC = 27/3 = 9 centimeters.
the perimeter of the triangle is the sum of all sides, i.e. AB + BC + AC
means AC = 61-27-9 = 25 centimeters
