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?
A
.
52
B.

C.
D.
56
To calculate the perimeter of the space that the homeowner wants to fence in, we need to add up the lengths of all the sides.
Side 1: 3 units
Side 2: 6 units
Side 3: 6 units
Side 4: 6 units
Side 5: 5 units
Side 6: 6 units
Side 7: 4 units
Side 8: 6 units
Side 9: 4 units
Side 10: 6 units
Side 11: 6 units
Adding all these lengths together:
3 + 6 + 6 + 6 + 5 + 6 + 4 + 6 + 4 + 6 + 6 = 54
Therefore, the homeowner will need 54 feet of fencing to build the dog pen. The answer is B. 54.
