I'm writing an essay about how Beethoven changed the game of composing and music in general. Anyone have any ideas or sources they recommend?

Sites like Britannica, the History site, and Khan Academy have lots of things on music.

Explanation:

hope that this can help you out!

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
