A homeowner wishes to put a fence around a space in her yard to create a dog pen. The space that she wants to fence in is shown below where each unit on the graph represents one foot.
How many feet of fencing will the homeowner need to build the dog pen?
To figure out the length of fencing needed, calculate the perimeter of the space shown in the graph.
Counting the sides and adding their lengths:
- Left side: 5 units
- Top side: 7 units
- Right side: 5 units
- Bottom side: 6 units
Adding these lengths together:
5 + 7 + 5 + 6 = 23
Therefore, the homeowner will need 23 feet of fencing to build the dog pen.
