How many acres is 720m x 359m x 432m x1000m?

Answer 1

It is not possible to provide a sensible answer.

Since there are four measures given it is assumed that the area in question is quadrilateral. Unfortunately, a quadrilateral is not a rigid figure and can be flexed so that its are changes. This is a bit like a square being flexed into a rhombus which can then be made to have as small an area as you like.
