I think you mean "ratio", not "raito." Ummm... The answer is 30 models that were sold
To find the area, we need the height of the triangle first. We already have the base.
Let's find the height (BA)
tan = opposite / adjacent
tan 35 = BA / 12
BA = 12 * tan35
BA = 12 * 0.7002079283708176
BA = 8.402
Area of the triangle = 12*BA/2 = 6*BA = 50.412 square units
