what is A = 37.5 cm 2,b = 8 in.;h =

It is not too clear what your question is about.
If it is about a triangle with Area = A, base=b and height=h, then the height h can be found from the formula:
Area of triangle = (1/2)bh
or h=2A/b.
However, the figure could be a parallelogram, a retangle, etc. in which case the above formula does not apply.
