The sides of the triangle are in the ratio 3: 4: 5. Find the perimeter of a similar triangle if one of the sides is 15 cm and is the largest.
Since the large side of such a triangle is 15 cm, its smaller side is equal to:
15 * 3/5 = 9 cm, and the middle side is 15 * 4/9 = 12 cm.
Rtr = 15 + 9 + 12 = 36 cm.
Answer: The perimeter of the triangle is 36 cm.
