Perimeter = sum of three sides = 96 cm
One side of 34cm, another of 25 cm so the third is 96 - 34 -25 = 37 cm
The perimeter is the sum of the three sides.
Side # 1 - 40Side # 2 - 20Side # 3 - 16
The lengths of two sides are not enough to determine the perimeter of a triangle: Either the third side or else the angle between the two given sides is also needed. If two of the sides are 10m and 25m, then the third side can be anything between 15m and 35m, and the perimeter can be anything between 45m and 70m.
11 centimeters 15 centimeters and 17 centimeters can form a triangle . It is because some of any two sides of triangle is greater than the third side . a + b >c always.
Perimeter of the isosceles triangle: 16.2+16.2+8.1 = 40.5 cm

You cannot discover the perimeter of a triangle if all you have is the length of two sides and nothing else. Knowing only the length of two sides of a triangle is insufficient to discover the length of the third side, and, thereby, discover the perimeter. Use the link below to a related question and see how it works.
To get the perimeter, you need to add all three sides. I assume you can get the third side by inserting the numbers you know into Heron's formula.
The perimeter of a triangle is side A plus side B plus side C. Since we are talking about a right triangle, if you know two sides, then you know the third by the Pythagorean Theorem: A2 + B2 = C2
No. The sum of the lengths of two sides of a triangle must always at least slightly exceed the length of the third side, and the given numbers do not conform to this rule.
Surely you know how to find the third side of a right triangle, when you know the lengths of the other two. Find it, and then add up the lengths of the three sides to get the perimeter.
Subtract the two side lengths from the perimeter. The perimeter of a triangle is just the length of the 3 sides added together. Eg. Q: A triangle has a perimeter of 20 m. One side is 5m and another is 10m. How long is the 3rd side? A: Perimeter - side 1 - side 2 = side 3 Side 3 = 20 - 5 - 10 = 5 m
