In Triangle ABC, side AB is 5.2 cm. It is less than side BC by 1.9 cm, but more than side AC by 2.6 cm. Find the perimeter of triangle ABC.
Let us determine the length of the BC side.
BC = AB + 1.9 = 5.2 + 1.9 = 7.1 cm.
Determine the length of the AC side.
AC = AB – 2.6 = 5.2 – 2.6 = 2.6 cm.
Let’s define the perimeter of the triangle ABC.
Ravs = AB + BC + AC = 5.2 + 7.1 + 2.6 = 14.9 cm.
Answer: The perimeter of the triangle is 14.9 cm.
