Questions are related to the using formulas for the surface area, length of diagonals, the relationship between sides and the diagonals, and the perimeter.
Usually the length of perimeter or diagonal or the area is to be calculated and then the price or cost is to be found. Also the amount of material required given the sizes.
Or, the size of the quadrilateral is to be estimated when given the cost limits and other specifications, during design.
