Trapazoid area=(top+bottom)*hite/2
bottom=33, top=20, ends=14 & 15
differ tween top & bottom=13
=sum av lengths av base av the triangels at 2 ends (make rite triangels)
put 2 triangels tugether, yu hav nu triangel with base=13, & other sides=14 & 15
angels=59.48976, 53.1301, 67.38014 deg
triangel area=84, so hite=84/14=6
(get triangel area from Herons formula)
trapazpod area=6*(33+20)/2
=3*53=159
