Hello,Originally Posted by AirForceOne
let H be the height of the trapezoid and h the height of triangle(ZYP) (I#ve attached a diagram to demonstrate, what I'll calculate).
Then you get the proportion:
. Solve for h and you'llget h = 4/7*H.
to e.: You get the area of triangle(XPY) by:
to d.: As I've shown above you can calculate the areas of the triangles in question by calculating the differences of two triangles.
Unfortunately I'm a little bit in a hurry to complete the problem, but I'm certain that you now know how to handle the problem.
Greetings and Happy Easter to you.
