Answer:
4 feet and 9 inches
Step-by-step explanation:
first you want to take the 11 inches from the 9 but you can't so you would take the 3 missing inches from the 10 foot and that would make it 9 feet and 9 inches
then take 5 from the left over 9 and that is 4 so your answer would be 4 feet and 9 inches
