**Reiny**, Saturday, October 1, 2011 at 6:04pmUsing Calculus:

Area = ∫(x+3) dx from 8 to 15

= [x^2/2 + 3x] from 8 to 15

= 225/2 + 45 - 64/2 - 24

= 203/2 or 101.5

of course we don't need Calculus to do this, since the shape is a simple trapezoid

at x=8, height = 11

at x = 15 , height = 18

distance between = 15-8 = 7

Area = (1/2)(11+18)(7) = 101.5
