Applying the equation for the area of the trapezoid, it is found that the height is of 10 cm.

The area of a trapezoid is half the multiplication of the sum of the bases and the height, that is:

$A = \frac{h}{2}(b_1 + b_2)$

For this problem, we have that: $A = 205, b_1 = 20, b_2 = 21$ , hence:

$A = \frac{h}{2}(b_1 + b_2)$

$205 = \frac{h}{2}(20 + 21)$

$20.5h = 205$

$h = \frac{205}{20.5}$

$h = 10$

The height is of 10 cm.
