While measuring the area of a plan using a planimeter, the following ...
Area of the map, A=M[ Final reading − Initial reading±10N+c]
View all questions of this test
Where M = multiplying constantly.
N = No of revolution passes the zero mark [ + ve for clockwise and –ve for anti-clockwise revolution]
C = Constant of index arm = 0; when the anchor point is outside the plan
A=100×[8.378−1.378+10×1+0]
= 1700cm2

While measuring the area of a plan using a planimeter, the following ...
To determine the map area using a planimeter, we need to consider the initial and final readings of the instrument. In this case, the initial reading is 1.378 and the final reading is 8.378.
The multiplying constant for the planimeter is given as 100 cm². This means that for every unit on the planimeter scale, the actual area measured is 100 cm².
To calculate the map area, we need to find the difference between the final and initial readings and multiply it by the multiplying constant.
Calculation:
Map area = (Final reading - Initial reading) * Multiplying constant
= (8.378 - 1.378) * 100 cm²
= 7 * 100 cm²
= 700 cm²
Therefore, the map area is 700 cm².
However, it is important to note that the question states that the anchor point was outside the plan and the zero marks of the disc were crossed once by the index in the clockwise direction. This means that the direction of the measurement was clockwise.
Considering the clockwise direction, the disc crosses the zero mark once in the clockwise direction. This implies that the area measured is negative.
Since the question does not specify whether the measurements are in square centimeters or square units, we can assume that the measurements are in square units.
Therefore, the correct map area is -700 square units.
