A rectangular plot of land measures 30cm × 40cm on a village map drawn to a scale of 100 m to 1 cm. Calculate its area in hectares. If the plot is re-drawn on a topo sheet to a scale of 1 km to 1 cm, what will be its area on the topo sheet? Also determine the R.F. of the scale of the village map as well as on the topo sheet.

The distance between two stations was measured with a 20m chain and found to be 1500 m. The same was measured with a 30m chain and found to be 1476m. If the 20m chain was 5cm too short, what was the error in the 30m chain?
