Example Question #23 : Perimeter Of A Triangle
What is the perimeter of an equillateral triangle with side of length 5.5cm?
The formula to find the perimeter of a triangle is
where a, b, and c are the sides of the triangle. We know that one side of the triangle is 5.5cm. We also know that an equillateral triangle has 3 equal sides. Therefore, all sides are 5.5cm. Using that information, we can substitute into the formula. We get
Note that we do not combine the labels, only the coefficients.
Example Question #83 : Perimeter
What is the perimeter of an equilateral triangle with a base of 6 feet?
Cannot be determined from the information provided
What is the perimeter of an equilateral triangle with a base of 6 feet?
Perimeter is simply the distance around the outside of a shape.
We are asked to find the perimeter of an equilateral triangle. In other words, the three sides must be the same length. In other words, we have three sides, each 6 feet long.
So our answer is 18ft.
Example Question #345 : Geometry
An isosceles triangle measures 
To find the perimeter of any object, simply add the length of each side together. This triangle has sides of 4, 4, and 7, so the answer is:
