Example Question #641 : Geometry
A square has a perimeter of , what is the lengthh of one side?
The perimeter of a square is the sum of all of its sides. Since a square has four equal sides, the length of one side can be multiplied by four to find the perimeter.
In this problem, however, we are given the perimeter and must find the side.
Therefore, we should divide to find the missing side.
Example Question #1 : Triangles
The perimeter of a triangle is 14 inches. One side is 4 inches long. Another side is 5 inches long. How long is the 3rd side?
Add up all of the sides of a triangle to get the perimeter. Here, 2 of the sides add up to give you 9 inches. The third side must equal the difference between 14 inches and 9 inches.
Example Question #2 : Triangles
Bill found the perimeter of the triangle below to be 34 units.
What is the length of the missing side?
15 units
13 units
12 units
20 units
14 units
14 units
The perimeter of a triangle can be found by adding up all of the sides.
Start by adding the two sides that are given: 8 + 12 = 20
The third side can be found by subtracting this sum from the total perimeter: 34 - 20 = 14. The missing side is 14 units long.
Example Question #3 : Triangles
Zoe drew the below triangle.
What is the perimeter of the triangle?
36 inches
39 inches
20 inches
30 inches
40 inches
39 inches
The perimeter of a triangle can be found by adding all of the side lengths: 8 + 12 + 19 = P. Therefore, the perimeter of the given triangle is 39 inches.
Example Question #4 : Triangles
Megan drew the triangle below and found its perimeter to be 36 inches.
What is the length of the missing side?
15 inches
36 inches
12 inches
21 inches
9 inches
9 inches
The perimeter of a triangle can be found by adding up all of the sides.
Start by adding the two sides that are given: 15 + 12 = 27
The third side can be found by subtracting this sum from the total perimeter: 36 - 27 = 9. The missing side is 9 inches long.
Example Question #5 : Triangles
James found the perimeter of the triangle to be 95 cm.
What is the length of the missing side?
To find the perimeter of a triangle, add the lengths of the three sides together. In the given triangle, . Combine like terms and solve for in order to find the length of the missing side:
The missing side is long.
Example Question #5 : Triangles
What is the perimeter of the above triangle?
To find the perimeter of a triangle, add up the lengths of the three sides:
Example Question #642 : Geometry
What is the perimeter of the triangle below?
To find the perimeter, we add all of the side lengths together.
Example Question #6 : Triangles
What is the perimeter of the triangle below?
To find the perimeter, we add all of the side lengths together.
Example Question #7 : Triangles
What is the perimeter of the triangle below?
To find the perimeter, we add all of the side lengths together.
