18000 = (250/2) h
so h = 144
now you can find length of OW or IA easily as hypotenuse of right triangle of height 144 and base 25
call that center intersection C
triangle OIC is similar to triangle WAC (isoceles with same top angle) so all sides are in the same ratio
of 100/150 including all altitudes. That does it :)
the area of a trapezoid cornfield IOWA is 18000 sq m The100 meter side IO is parallel to the 150 meter side WA. This field is divided into four sections by diagonal roads IW and OA. Find the areas of the triangular sections
