A gardening company would like to predict the density of the weed population in a yard before it is sprayed with pesticide. The yard measures 200 cm × 100 cm. The gardener  places four 2.0 cm × 1.0 cm quadrats randomly in the park, and calculates the weed counts of 22, 46, 32 and 40 weeds in the 4 quadrats. Solve for the density of the weed population.
