Answer 2

Calculation of Perimeter of Triangle ABC

To calculate the perimeter of triangle ABC, we need to find the sum of the lengths of its three sides. Given that AB = 3/2 cm and BC = 6/5 cm, we can find the length of AC by adding AB and BC.

Let's calculate the length of AC:

AC = AB + BC

Substituting the given values:

AC = 3/2 cm + 6/5 cm

To add these fractions, we need to find a common denominator. The least common multiple of 2 and 5 is 10.

AC = (3/2 * 5/5) cm + (6/5 * 2/2) cm

AC = 15/10 cm + 12/10 cm

AC = (15 + 12)/10 cm

AC = 27/10 cm

Now that we have the length of AC, we can calculate the perimeter of triangle ABC by adding the lengths of all three sides:

Perimeter = AB + BC + AC

Substituting the given values:

Perimeter = 3/2 cm + 6/5 cm + 27/10 cm

To add these fractions, we need to find a common denominator. The least common multiple of 2, 5, and 10 is 10.

Perimeter = (3/2 * 5/5) cm + (6/5 * 2/2) cm + (27/10 * 1/1) cm

Perimeter = 15/10 cm + 12/10 cm + 27/10 cm

Perimeter = (15 + 12 + 27)/10 cm

Perimeter = 54/10 cm

Simplifying the fraction:

Perimeter = 27/5 cm

Therefore, the perimeter of triangle ABC is 27/5 cm.

Answer: The perimeter of triangle ABC is 27/5 cm.
