Example Question #34 : Triangles
The perimeter of a scalene triangle is 21 mm. Which choice shows the correct side lengths?
When finding the perimeter of any triangle, you will need to add all three sides. In this case, it is important to note that this is the perimeter of a scalene triangle. A scalene triangle has no congruent/equal sides. The only choice that adds up to 21 mm with no equal sides is:
Example Question #623 : Geometry
What is the perimeter of the above triangle?
12
28
30
7.5
11
12
To find the perimeter of a triangle, add all of its three sides. 5 + 4 + 3 = 12
Example Question #35 : Triangles
If the blue triangle has three equal sides, what is the triangle's perimeter?
Since the problem asks about an equilateral triangle (one that has three equal sides), we just need to multiply the given side's length by 3.
Example Question #7 : How To Find The Perimeter Of A Triangle
What is the perimeter of the above triangle?
16
48
28
24
32
24
To find the perimeter of a triangle, simply add all three sides together.
Example Question #625 : Geometry
A triangle has a perimeter of inches. If all its sides are the same length, what is the length of one of its sides?
inches
inches
inches

inches
A triangle has sides, and its perimeter is the length of all the sides added together. Since all the sides are the same length, dividing the perimeter by will give the length of one side. divided by is inches.
Example Question #626 : Geometry
You can find the perimeter of a triangle if you know __________.
three side lengths
its angles
the height and base
the area
three side lengths
Example Question #36 : Triangles
What is the perimeter of the triangle?
To find the perimeter of a triangle, simply add all three sides together.
Example Question #41 : Triangles
The perimeter of an isosceles triangle is 22 mm. Which choice shows the correct side lengths of the triangle?
An isosceles triangle has two equal sides, and one different side. All of the answer choices add up to 22 mm, but only one choice shows two equal sides and one different side that add up to 22mm.
Example Question #42 : Triangles
An equilateral triangle is a type of triangle that has sides that are each of the same length. If one of the sides of an equilateral triangle is units long, what is the perimeter of the triangle?
units
units
units
units
units
units
Since an equilateral triangle has three equal sides, the total perimeter of the triangle is units, since each side is units long and .
Example Question #43 : Triangles
A triangle has sides of three different lengths. One of its sides is units long. Another of its sides is units long. The third side is of a length that is the average of its other two sides. What is the perimeter of this triangle?
We know two of the lengths of the triangle's sides: and . We are also told that its third side's length is an average of its other two sides. We can find the average of and by adding them together and dividing by two: and , so the triangle's third side has a length of . We can now find the perimeter of the triangle by adding up the lengths of its sides: , so the perimeter of the triangle is .
