Hellp pwease!
which of the foundational musical elements is best defined as "the forward movement of music in time"?
(a) variety
(b) melody
(c) rhythm
(d) harmony

well no because those options are in a house

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

the correct answer is option a. i just did the quiz and the first painting was correct.

hope this and good luck! < 3
