Final answer:
To find the total length of fencing, sum the lengths of each side. The lengths are 12' 3 1/2", 12' 3 1/2", and 24' 5 3/4". After adding, the total fencing length is 49 feet and 0.75 inches.
Step-by-step explanation:
The question involves calculating the total length of fencing added to a backyard, which is a basic arithmetic problem often encountered in mathematics. Let's find the total length of the fence by adding up the individual lengths of the three sides.
- 12' 3 1/2" = 12 feet and 3.5 inches
- 12' 3 1/2" = 12 feet and 3.5 inches
- 24' 5 3/4" = 24 feet and 5.75 inches
First, you add up the feet part of the measurements and then the inch part separately:
12 feet + 12 feet + 24 feet = 48 feet
Now, add the inches:
3.5 inches + 3.5 inches + 5.75 inches = 12.75 inches
Since there are 12 inches in a foot, 12.75 inches equal 1 foot and 0.75 inches. Now we can combine the total feet and inches:
48 feet + 1 foot = 49 feet and 0.75 inches
Therefore, the total length of the fence is 49 feet and 0.75 inches.
