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 you find the perimeter of a triangle if you know the area?

You cannot. For a given area, an equilateral triangle will have the smallest perimeter but that perimeter can be increased - without limit - without increasing the area.


What is the formula for perimeter of a right triangle when one side is missing?

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.


What do you do to find the perimeter of a triangle?

The perimeter of a triangle is equal to the length of its three sides added together. If you do not know the lengths of the sides, there are many different mathematical techniques for discovering them.


How can you find the area if you know the perimeter?

Only if you also know the shape and proportions. An equilateral triangle, for example.


Suppose you know the perimeter and the height of an equilateral triangle explain how you would find the area of the triangle.?

The base is one third of the perimeter, half of the base times the height is the area.


How do you find the unknown length of one side of a triangle when you know the perimeter and the length of the other two sides?

subtract the two sides that you know from the perimeter to get the unknown side.


Do you need the height to find the perimeter of a triangle?

Some times you do. If you know all of the side lengths, then you can just add them to find the perimeter, if one of the sides is the same as the height, then you may need to find it.


How do you find the perimeter of a triangle when two angles are given And one is a 90 degree angle?

Knowing only the angles of a triangle does not provide enough information to determine its perimeter. You must know the length of at least one side.


Find the area of a triangle that has a perimeter of 21 inches?

I need to know more about the triangle, such as one or 2 of the angles, whether it is isosceles or equilateral, or whether the lengths share a certain ratio. For example, a triangle of sides 8,8 and 5 (perimeter of 21) will surely have a different area as compared to a triangle of sides 7,7 and 7 (perimeter of 21 as well)
