The perimeter of a triangle is the sum of its three sides.
If two are 3m and 2m then their sum is 3m + 2m = 5m
And the remaining side can be calculated by taking this sum from the perimeter
→ the other side is 9m - 5m = 4m long.

Formula of perimeter of isosceles triangle?
Lengths of: equal side+equal side+base = perimeter
Do you use perimeter to solve the volume of a triangle?
I'm assuming that you mean the area of the triangle. You do not need the entire perimeter. The formula is 1/2 bh. b=base, h=hight
Base of triangle is 10km and height is 12km what is the perimeter of this triangle?
There are many different triangles with a base of 10 km and height of 12 km, and they have different perimeters. The smallest perimeter occurs if the third vertex is directly above the midpoint of the base; then the altitude from that vertex divides the triangle into two congruent triangles with sides 5, 12, and (by the Pythagorean theorem) 13. The sides of length 12 are shared, so the perimeter of the triangle is 36 km in this case. If the third vertex is moved to one side but kept at the same height, the perimeter increases; there is no upper bound on the perimeter that can be achieved.
How do you get the height of a triangle?
To find the height of a triangle you measure it. It has to be from the middle of the base to the top point.
If DEF is an isosceles triangle with base what is the measure of F?

How do you measure areas and perimeter from a triangle?
For the area you just multiply base by height and divide by 2. For the perimeter you just add all the lengths together
Formula of perimeter of isosceles triangle?
Lengths of: equal side+equal side+base = perimeter
How do you find the area and perimeter of a triangle?
Area:A=1/2bhA=Area b=Base h=HeightPerimeter:P=a+b+cP=Perimeter a,b,c=side lengths of the triangle
What is the area and perimeter of a triangle 19cm x 21 cm?
To find the area of a triangle, you need the length of the base and the height. If the triangle has a base of 19 cm and a height of 21 cm, the area would be (1/2) * base * height = (1/2) * 19 cm * 21 cm = 199.5 cm^2. To find the perimeter of a triangle, you need to add the lengths of all three sides. Without knowing the lengths of the other sides, the perimeter cannot be determined.
How do you find the perimeter of triangle?
Find the lengths of the sides, and add up the three numbers.
How do you find the perieter and area of a triangle?
The perimeter of an object is simply the length of its border, so the perimeter of a triangle is the sum of the lengths of its 3 sides.The area of a triangle is equal to half of its base times its height, for example if a triangle had a base of length 4 and was 5 units tall, it would have an area of (4*5)/2, or 10 units2.
How do you measure area perimeter?
If you're trying to measure the perimeter of almost any shape like a square or triangle or octagon, simply count all the unit measurements of each side and add them together. If the unit your measuring is unknown, then leave it as units. For example, if you were finding the perimeter of a rectangle that has the measurements 6units, 6units, 4units, and 4units, the perimeter would be 20units. I hope this helped :)
What is the formula of finding perimeter of isoceles triangle?
Assuming the lengths of the sides are given, then perimetrer = base + 2*leg If the sides are not given, then the answer will depend on what information is provided.
A triangle has a base of length 20 units and perimeter of 66 units. If a similar triangle has a base of 15 units what is its perimeter?
49.5 units
If the base of an isosceles triangle is 11 and the perimeter is 39 what is the length of a leg?
If the base of an isosceles triangle is 11 and its perimeter is 39, then it has a height of 12.87.
The isosceles triangle had a side of 4.6 inches and a base of 3.9 inches. What was the distance around it?
An isosceles triangle is a triangle with two equal sides. To find the perimeter of the triangle, you simply need to add together the lengths of the base and the two sides. So: 3.9 + 4.6 +4.6 = 13.1 inches.
How do you find the perimeter of a isoscles triangle all you know is the base and height?
-- Imagine what you have if you slice the triangle in half along the height ...-- You have a right triangle. One side of it is 1/2 of the base, and one side isthe height.-- The slanting side is the hypotenuse of the right triangle, and knowing whatyou know about right triangles, you can calculate its length.-- Once you do that, you have the lengths of all three sides of the original triangle,and you can calculate the perimeter.
