Estimating trion
We used mathemaitcal modeling to estimate the amount of trion in our map.
We determined that the map area is about 13% trion. Here's how we used mathematical modeling to get this estimate.
Experience/issue
The issue is Trion is a invasive spices of grass that dies faster then normal grass. It is a problem because it is a fire hazard for the sounding area. In the picture, the brown grass is trion.
Our mathematical question
Our question is what is the percentage of Trion in the map area.
Assumptions
We are assuming all the light brown on the map is Trion.
How math helped us answer our question
Math helped us answer what percentage of Trion there was. We got the number by turning the map into a grid and counted the whole squares of Trion and halves
Our mathematical solutions
First estimates of percentages based on a quick look
We all estimated the precentage based on a quick look. Our estimates were:
40% C
10% S
25% F
30% M
50 %
68 % D
Refined estimates based on a careful count
Three of us estimated using a careful count of wholes and halves. Our estimates were:
15% F
13 % J
9.2 % D
We think it's about 13% trion because it's in the middle of the estimates
There are 184,900 square feet, or 4.25 acers.
13% is 24,037 square feet, or 0.56 acers.
Perimeter
We also estimated the perimeter of the trion. Here's the calculation.

Each square is 10m, so the perimeter is 1060m
