What makes hot jazz unique with the use (or non-use) of improvisation?

Improvisation is emphasized in hot jazz. Hot jazz is unique because unlike other types of jazz, multiple musicians engage in strong rhythms and fiery improvisation all at the same time. This genre of popular music is emotionally charged and intense, and is delivered with blazing tempos.

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
