The paper of an old map drawn to a scale of 100 m to 1 cm has shrunk, so that a line originally 10 cm has now become 9.4 cm. There was also a note on the plan that survey done with a Gunter’s Chain was 10 cm too short. If the area measured now is 65 sq- cm.
Find
the correct area on the ground in sq- cm and sq- km.?
