Look for important information
Here is the information we need to know:
- The golf course has 6 sides.
- The perimeter is 930 ft.
- 1st side: 82 ft.
- 2nd side: 93 ft.
- 3rd side: 225 ft.
- 4th side: 230 ft.
- 5th side: 100 ft.
- We need to find the length of the 6th side.
Write a math sentence.
Use a piece of paper to draw a picture of the golf course. It should look something like this:

Now let’s set up our equation!
\({\Large82 + 93 + 225 + 230 + 100 + \text{?} = 930 }\)
Solve and label your answer.
Find the missing length by solving the equation.
First, add the known lengths together:
Now subtract the sum of the known lengths from the perimeter:
Don’t forget to label your answer!
You did it! The missing side of the golf course is 200 feet long.
Now it's your turn! Can you find the perimeter in this word problem?
A miniature golf course has 4 sides and perimeter of 62 feet. One side is 10 feet long, one side is 22 feet long, and another side is 18 feet long. What is the length of the remaining side of the miniature golf course?
- 12 ft
- 15 ft
- 10 ft
Correct! The length of the remaining side is 12 ft.
You can find the missing length by adding the sides together and subtracting the sum from the perimeter!
