Please Help! I am not sure how to do this, please help walk me through it, thank you! I will post a picture below. It is finding the height of a parallelogram in geometry

OpenStudy (bookworm14):

jimthompson5910 (jim_thompson5910):

imagine you tipped the parallelogram so that it rotates where the "36" side is now the base, ie the flat horizontal side if 36 is the base, what is the height?

OpenStudy (bookworm14):

would it be the 24?

jimthompson5910 (jim_thompson5910):

yes, so what is the area of the parallelogram?

OpenStudy (bookworm14):

144 ? (base times height)

jimthompson5910 (jim_thompson5910):

base*height = 36*24 = 864

OpenStudy (bookworm14):

i meant 864, my bad haha

OpenStudy (bookworm14):

divide that by 27 to get 32?

jimthompson5910 (jim_thompson5910):

so we know the area of the parallelogram is 864 square units if we made 27 the base now (going back to the original drawing), we'd have h as the unknown height so, A = b*h 864 = 27*h solve for h to get h = 864/27 h = 32 yes you would divide that area by 27

i was struggling over something so simple, oh my goodness thank you so much!

no problem
