This is asking you to use Simpson's rule to calculate the area between the

axes and a curve which passes through the points (0,14), (h,16), (2h,15), ..., (18h,6).

This is:

A=(h/3)[14+4x16+2x15+4x15+ ... +4x6+6]=(h/3)x622,

but as it seems to be keeping the value of h to itself there does not seem to be much more that can be done.
