Final answer:
To find the total length of fencing needed to enclose the dog pen, we calculate the perimeter of the pen by adding up all the sides. The given dimensions are converted to meters for uniformity. The total length of fencing needed is 11.5 meters.
Step-by-step explanation:
To find the total length of fencing needed to enclose the dog pen, we need to calculate the perimeter of the pen. The given dimensions are 4m and 175cm. To ensure uniformity, we'll convert all the measurements to meters.
4m = 4m
175cm = 175/100 = 1.75m
Now, to calculate the perimeter, we add up all the sides:
Perimeter = 4m + 1.75m + 4m + 1.75m = 11.5m
Therefore, 11.5 meters of fencing will be needed to enclose the dog pen.
