John counts 50 ladybugs at the local park in a 10 square meter area how many lady
bugs are in the park

To solve this with an exact answer, we would need the area of the park (size in square meters of the park). From this question, all we can solve is that, by dividing the number of ladybugs by square meters (50/10), there are 5 ladybugs per square meter, or l=5a, l being ladybugs and a being area in square meters.
