No, your answer should be,
[tex]\Huge\boxed{288}[/tex]
To convert feet into inches, you multiply the length value by 12. Your mistake is you got it mixed-up. 24ft doesn't equal 2in, but 24in equals 2ft, because instead of multiplying 12, you divide by 12.
24ft → 288in
24 × 12 = 288
24in → 2ft
24 ÷ 12 = 2
Hence, 24ft doesn't equal 2in.
