It is not possible to answer the question. The fact that there are four lengths suggests that the lot is a shape in 4-dimensional hyperspace. In that case I not sure that a meaningful measure of the total square footage can be given. Al alternative is that these are the measures of the four sides of a quadrilateral. A quadrilateral is not a rigid shape. It can be flexed through infinitely many shapes - from a thin long shape to a near rectangle and the area will vary hugely according to the shape. It is, therefore. not possible to calculate the square footage.
