In the integral, the function f(x) = 0.5 x, and therefore the integral has the form: A = ab c x dx Where A is the area under the line; A is the area of the shaded trapezoid in the figure above. What are the values: a = 6 b = 14 c = 0.5 (express as a decimal to one place) What is the area, A, of the shaded (trapezoidal) region
