Four men were hired to perform weeding in a field having a length to width ratio 4:1 using manually operated weeders. The field has a width of 3o m and is planted with corn. Before the weeding operation, it was determined that field has an average plant population of 5 corn plants per linear meter and an average weed population of 15 weeders per meter squared. After 8 hours of operation, average of 1 corn plant was damaged per 4 meter squared of area and an average of 13 weeds were removed per square meter. Determine the weeding index and the performance index of the operation if the row spacing is 50 cm. Formula: Weeding Index = (W1-W2)/W1 ×100 where W1 = total population of weeds before the operation W2 = total population of weeds after the operation
