    To find area from known perimeter
    I have a problem to find area from a known perimeter of a irregular shape.
    For example I have a shape measuring 255m. How much will be the perimeter in meter? Please show me how to calculate the area from this known perimeter?

    Big difference between 126.5 and 5174.5
