area of TRAPEZIUM

Question

IF TWO PRALLEL SIDES OF A TRAPEZIUM ARE 33CM ,20CM AND NON PRALLEL SIDE ARE  15 AND 14 FIND ITS AREA

Answer 1

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
