Answer:
The total length of three sides is 62'-1"
Step-by-step explanation:
We know that 1 foot = 12 inches and 1' = 12''
Part 1)
We also know that side 1=15'-7", side 2=20'-4", side 3=26'-2"
To find the total length of three sides sum the three sides
So the total length=side 1+side 2 +side 3
Now we substitute
Total length=15'-7"+20'-4"+26'-2"
Total length=(15'+20'+26')+(7"+4"+2")
Total length=(61')+(13")
Remember that 12"=1'
13"=12"+1"=1'+1"
Substitute again
Total length=(61')+(1'+1")
Total length=(62')+(1")---------> 62'-1"
Therefore the answer is the total length of three sides is 62'-1"
