Hey Mr. Bruce,

On the second sheet I am able to calculate a trapezoid by adding cells.

I guess what I am asking is how do I write a formula for calculating a
trap. Without adding the cells. I am not able to do it with the right
and left functions. I am not sure how to code it.
Say for example I want the dimension in cell C15 "x 15" I do not know
how to pick it up for calculation in the trapezoid.

I hope that makes sense.
