let :

5 cmdrawing = 25 mReal

thus (it is okay to divide both sides by 5 since the scale is linear)

1 cmdrawing = 5 mReal



Width = 6.8cmdrawing * (5 mReal / 1 cmdrawing) = 34 mReal

Length = 12.3cmdrawing * (5 mReal / 1 cmdrawing) = 61.5 mReal


Area = Width * Length = (34 mReal ) * (61.5 mReal ) = 2091 m2
