Planimeter.
Was laid on the table in the laboratory and ended when an area measurement for the sample was obtained either (lirectly or by calculation all measurements whether made by 1 or 2 operators, were converted to man/seconds per leaf in using the blue-print and planimeter method on grass leaves it was found that area. Now move the pointer of the planimeter around the whole figure and then note down the reading of the vernier callipers take more readings by the planimeter and calculate the area by the formula take down the average reading procedure : 7 lab work : 8 calculation : area = m(fr-ir + 10n + c).
