In triangle ABC, side AC is 2 times larger than side AB and 2 centimeters larger than side BC Find the perimeter of triangle a b c if it is known that A B is 6 cm.
If AB = 6 cm and AC = 2 * AB, then AC = 6 * 2 = 12 centimeters.
Since BC = AC – 2, then BC = 12 – 2 = 10 centimeters.
The perimeter (P) of a triangle is the sum of the lengths of its sides:
P = AB + AC + BC.
P = 6 + 12 + 10.
P = 28.
Answer: P of triangle ABC is 28 centimeters.
