Your search for Determine the number of square meters of vinyl needed to line the inside of a right rectangle swimming pool. The pool is 7m long, 4m wide, and has a uniform depth of 2.5m returned no results.
This doesn't make any sense to me.
Are you looking for the total surface area of the inside of the pool?
If that is the case, just use length x width x height for each side of the pool and the bottom and add them together to get the total, there is probably an easier way to do this but it is just how I have always done it.
