<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>
I don't know what c you are talking about because there is no picture
(X 3-y) (3+z)
That's the two polynomials
9 squares because if there are 18 triangles in it then you divide 18 by 2 and get 9
