The sum of the two sides of the triangle is 36 cm, and the length of the third side is 75% of this sum.

The sum of the two sides of the triangle is 36 cm, and the length of the third side is 75% of this sum. Find the perimeter of the triangle.

1. First of all, it is necessary to find out the length of the third side of the triangle, if it is known that it is 75% of 35 cm. Then we find 75% of 35 cm and find out the length of the third side:
(36 cm / 100) * 75 = 75 * 36/100 = 27 cm.
2. Now let’s find out the length of the perimeter of the triangle, adding the sum of the first two sides with the length of the third side of the triangle, we get:
36 + 27 = 63 cm.
Answer: As a result, we got that the triangle has a perimeter of 63 centimeters.
