The area of a trapezoid is calculated using the formula:
where
B is the length of the major base
b is the length of the minor base
h is the height of the trapezoid

B = 2 cm is the length of the top base
b = 4.5 cm is the length of the bottom base
is the area of the trapezoid
Solving for h, we can find the height of the stained glass window:
