What is the population density of 13 lillies living in an area of 6 meters (length) and 4 meters (width)?

0.54 lillies per square meter.

Step-by-step explanation:

First we calculate the area:

Area = length * width

Area = 6 m * 4 m = 24 m²

The we divide the population of lillies (13) by the area, to calculate the population density:

13 lillies / 24 m² = 0.54 lillies/m²

So the population density is 0.54 lillies per square meter.

answer: the answer is 40.82

step-by-step explanation: 3.14 x 13(or half of 26) to the power of 2
