In D. C. alcoda or D. S. alcoda, what is the name of the final section that ends the song?

Explanation:

The instruction D.C. will be followed by further instruction such as al Fine (to the finish) or al Coda (to the coda). D.C. al fine means to go back to the beginning of the music and play to the instruction “fine” (pronounced “feen”) which signifies the end of the music.

perimeter = 2l +2w, divide total perimeter by 2 for total length of 1 side and 1 width

172/2 = 86 (  total for 1 side and 1 width)

86-24 = 62 (since length is 24 ft longer subtract 24 then divide by 2 for width)

62/2 = 31

width = 31 feet

length = 31 +24 = 55 feet

check: 31*2 = 62, 55*2 = 110,  110+62 = 172
