Question 38284: The bases of an isosceles trapezoid are of lengths 12 and 28. The area is 300. Find the length of a diagonal. i keep working this one and getting the square root of 1009. i think i tried to use the pythagorean theorem after finding the height which i found to equal 15. Answer by fractalier(6550) (Show Source):
You can put this solution on YOUR website! Yes the height is 15. Good.
Now the diagonal is the hypotenuse of a right triangle with a base of 20 and height of 15. The 20 is found by subtracting 8 from 28.
So we have a 15 - 20 - 25 right triangle (really a 3-4-5).
Thus the diagonal is 25.
