Q.4

The area of an irregular figure was measured with a planimeter having the anchor point outside the figure. The initial and final readings were 5.835 and 9.354 respectively. The zero mark of the dial didn't pass the index mark during the measurement. The tracing arm was set to the natural scale (M=100cm²). The scale of the map was 1cm=10m. Find
