In triangle ABC, side BC is 23 cm, it is 6 cm longer than side AB and 6 cm less than side AC. Find the perimeter of the triangle.
The BC side is 23 centimeters and it is 6 cm larger than the AB side, which means that the AB side is 17 centimeters.
1) 23 – 6 = 17 (cm) side AB.
The BC side is 23 centimeters of the ion 6 cm less than the AC side, which means that the AC side is 29 centimeters.
2) 23 + 6 = 29 (cm) AC side.
The perimeter of a triangle is equal to the sum of all three of its sides (BC = 23 cm; AB = 17 cm; AC = 29 cm).
3) 23 + 17 + 29 = 40 + 29 = 69 (cm) perimeter of the triangle.
Answer: The perimeter of triangle ABC is 69 centimeters.
