In triangle ABC, side AB is 7.4cm. It is 3.6cm larger than the BC side. But less than the side AC

In triangle ABC, side AB is 7.4cm. It is 3.6cm larger than the BC side. But less than the side AC by 2.7 cm, which is equal to the perimeter of the triangle ABC.

1. Let us determine what the length of the BC side is equal to.

7.4 – 3.6 = 3.8 centimeters.

2. Let’s calculate the AC side.

7.4 + 2.7 = 10.1 centimeters.

3. Since the length of all sides of the triangle is known, and its perimeter is determined by the formula

p = a + b + c, let’s answer the question of the problem.

7.4 + 3.8 + 10.1 = 21.3 centimeters.

Answer: The perimeter of a triangle is 21.3 centimeters.
