What was so important about the Pope Marcellus Mass? Why was it so historically significant? (Palestrina)

Pope Marcellus Mass, Latin Missa Papae Marcelli, mass by Giovanni Pierluigi da Palestrina, the best known of his more than 100 masses. Published in 1567, the work is renowned for its intricate interplay of vocal lines and has been studied for centuries as a prime example of Renaissance polyphonic choral music.

Explanation:

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
