Answer:
9
Step-by-step explanation:
Fun fact. The name nonagon comes from Greek enneagonon, and is arguably more correct, though less common than "nonagon".
<span>a = 1/2 x b x h
h = 3b
so 1/2 x b x 3b = (1/2)(3b^2) = 150
(150 x 2)/3 = b^2
100 = b^2
b = square root of 100 = 10
h = 3b = 3 x 10 = 30</span>
