The answer to 9 feet 7 inches plus 11 feet 10 inches (9' 7" + 11' 10") is displayed below:
21 feet 5 inches
Here is how we calculated 9 feet 7 inches plus 11 feet 10 inches to get the answer above:
First, we converted feet to inches so we are only dealing with inches.
9 feet 7 inches = 115 inches
11 feet 10 inches = 142 inches
Then, we added the inches together to get the total number of inches:
115 + 142 = 257 inches.
Finally, we converted 257 inches into feet and inches to get the answer.
9' 7" + 11' 10" = 21' 5"
Note: There are 12 inches in a foot. Thus, you multiply feet by 12 to get only inches, and
to make it back to feet and inches we divided total number of inches by 12.
