ABSTRACT:
A system and method for determining area of irregular or complex shapes for easily determining area of complex shapes. The system and method for determining area of irregular or complex shapes includes comprises a quantity of tracing paper for capturing a two dimensional representation of the irregular shape, a quantity of a substrate having a known weight per unit of area, the substrate being for receiving a two dimensional representation of the irregular shape transferred from the tracing paper, and a scale for determining a weight of a two dimensional representation cut from said substrate.
