The perimeter of triangle ABC is 24 cm. The length of side AB is 35% and the length of side BC is 25%

The perimeter of triangle ABC is 24 cm. The length of side AB is 35% and the length of side BC is 25% of the perimeter of the triangle. Find the length of the AC side.

1. Determine the length of the side AB. We take the AB side as k and make up the proportion:

24 cm – 100%, to cm – 35%;

24: k = 100: 35;

k = (24 x 35): 100;

k = 8.4 cm.

2. Determine the side of the aircraft. We take the side of the BC as k and make up the proportion:

24 cm – 100%, to cm – 25%;

24: k = 100: 25;

k = (24 x 25): 100;

k = 6 cm.

3. Determine the sum of the sides AB and BC:

8.4 + 6 = 14.4 cm;

4. Determine the length of the speaker side:

24 – 14.4 = 9.6 cm.

Answer: 9.6 centimeters side length of the speaker.
