The answer to 10 feet 9 inches plus 1 foot 8 inches (10' 9" + 1' 8") is displayed below:
12 feet 5 inches
Here is how we calculated 10 feet 9 inches plus 1 foot 8 inches to get the answer above:
First, we converted feet to inches so we are only dealing with inches.
10 feet 9 inches = 129 inches
1 foot 8 inches = 20 inches
Then, we added the inches together to get the total number of inches:
129 + 20 = 149 inches.
Finally, we converted 149 inches into feet and inches to get the answer.
10' 9" + 1' 8" = 12' 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.
