In triangle ABC, side AB is 4.3 cm and it is 2.5 cm less than side BC, but 1.8 cm larger than side CA

In triangle ABC, side AB is 4.3 cm and it is 2.5 cm less than side BC, but 1.8 cm larger than side CA Find the perimeter of the triangle.

The perimeter of triangle ABC is:
P = AB + BC + AC;
Find the BC side:
1) 4.3 + 2.5 = 6.8 cm;
Find the side of the speaker:
2) 4.3 – 1.8 = 2.5 cm;
Knowing the lengths of the sides of the triangle, we can find the perimeter of the triangle:
3) 4.3 + 6.8 + 2.5 = 13.6 cm.
Answer: The perimeter of triangle ABC is 13.6 cm.
