Question

Quadrilateral ABCD is a trapezoid with an area of 20 cm2004-05-02-04-00_files/i0290000.jpg. Find the height of the trapezoid, h. Round the answer to the nearest tenth.

A.
4.0 cm
B.
5.0 cm
C.
5.7 cm
D.
10.5 cm

Answer 1

The answer cannot be determined if the two bases are not given. But here is the formula for finding the height of a trapezoid. Height or the altitude is equal to two times the area of the trapezoid  all over the sum of the two bases. 

Answer 2

A=(a+b)/2 x h
20=(a+b)/2 x h
h=(20x2)/(a+b)
h=40/(a+b)
i cant find out any pictures but all you need to do further is plug in the values of a and b.which is the base and the top side.
hope it works
