A new roadway 1

A new roadway 1.5 miles long is to be constructed through a currently wooded area. The right-of-way (R.O.W) or allowable width of working limits for this roadway will be 66 feet. It is your job to estimate work item quantities in order to develop a cost estimate. 

It is estimated that there are approximately 20 trees (10 inch in diameter or greater) per acre on this roadway that require removal. Compute the total number of trees to be removed from within the R.O.W. (conversion: I acre= 43560/r)
