Answer: 59 inches
Explanation: To convert feet and inches to inches, multiply the number of feet by 12 (since there are 12 inches in a foot) and then add the remaining inches.
Steps:
- Convert feet to inches: \( 4 \text{ feet} \times 12 \text{ inches/foot} = 48 \text{ inches} \)
- Add the remaining inches: \( 48 \text{ inches} + 11 \text{ inches} = 59 \text{ inches} \)
