What kind of triangle? if it's an equilateral triangle, then all the sides are of equal length, and the perimeter (all the way around) would be the sum of the three sides. If one side equalled x in length, then the perimeter would be 3x.

This only works for equilateral triangles (all three angles are 60 degrees because the sum of the angles of a triangle is 180, and 180/3=60), which is why you need to specify what kind of triangle you are talking about. Right triangles have one angle which is 90 degrees...... I'm guessing your textbook has more info on this. You might want to refer to it. However, since you asked how you FIND the answer rather than what is the answer to.... I'm willing to help some. :) Good luck.

How do you find the perimeter of a triangle with sides like 2x and 5x and 6x?

To find the perimeter of a triangle you have to add up all the sides. So to find the perimeter of this triangle you just add 2x+5x+6x=13x. To find the actual perimeter you would have to know what x equals


How do find the perimeter of a triangle?

The easiest way is if you already have the lengths of all three sides of the triangle. In which case, you simply add their lengths together to acquire the perimeter. However, if you only have the lengths of two sides of a triangle, and it's a right triangle"; you can use the Pythagorean Theorem to determine the length of the third side. Note: Here are some quick definitions of terms that will be used in the following equations. A² will represent the height of the triangle. B² will represent the width of the triangle. C² will represent the hypotenuse of the triangle. The "Hypotenuse" is the longest side of a triangle. A "Right Triangle" is a triangle that has an angle measuring 90°. When using the Pythagorean Theorem; if you're attempting to find hypotenuse of a triangle; you use the formula "A² + B² = C²". That is; you square the two known sides; then add the products. Upon doing that, find the square root of the sum of both numbers, and you have the length of the hypotenuse. Upon finding the missing side's length; add the lengths of all three sides, and the resulting number will be the perimeter of the triangle. If you have the length of one side, and the hypotenuse of a right triangle; and are seeking to find the third side's length; you use the formula "C² - A² = B²" or "C² - B² = A²"; depending on which side your attempting to find the length of. Like in the previous equation, add the lengths of all three sides together to acquire the perimeter.


What is the perimeter of the triangle if the short leg is 6 the hypotenuse is 12 and the long leg is 6radical 3?

that's easy...you just have to add 6 and 12. then you multiply the 6 times the radical 3 which is approximately 1.7. so 6+12=18 then 1.7x6=10.2. then you add 18 and 10.2 and you get 28.2. so the perimeter of the triangle is about 28.2 you would write it out like this: sides: 6+12+√3 perimeter: 18+√3= 28.2

What is the perimeter of a square with diagonal 12 centimeters?

The perimeter of a square with a diagonal of 12 centimeters is: 33.9 centimeters.In future, to find out the perimeter of a square when you only know it's diagonal, use Pythagoras or times the diagonal by 2.828427125.This number is irrational, and is like a pi for the diagonals of squares.I call it Tau.It is the relationship between the diagonal of all squares and there perimeter.


The side length of an equilateral triangle is x plus 3 write an expression for the perimeter of a triangle?

In an equilateral triangle, all 3 sides are the same length, so your equation would look something like this: P=the perimeter of the triangle (x+3)=length of each side P=3(x+3) If you wanted to simplify further, you would distribute the 3 to both the x and the 3 inside of the parentheses, giving you P=3x+9.


How do you find the area of a triangle with side lengths?

If you are only given the side lengths of a scalene triangle, it is impossible for you to find for the area, unless you are given more information... like the height of the triangle for example. If this is a right triangle you would like to find the area of, you can multiply the length of each leg with each other, and then divide that product by 2 to conclude the area of the triangle.

If a garden is shaped like an equilateral triangle and the perimeter is 36 ft how long in ft is one side of the garden?

Perimeter: total length of the shape, 36 ft.Equilateral Triangle: a shape with 3 sides, each equal in measure.36 ft/3 sides = 12 ft in length for one side (and for each of the other sides) of the garden.
