A fish and wildlife management organization uses a GIS (Geographic Information System) to store and analyze data for the parcels of land it manages. All of the parcels are mapped on a grid in which 1 unit represents 1 acre.

c. 133 acres

Step-by-step explanation:

Given: coordinates of the corners of a parcel are (-8, 10), (6, 17) and (2, -4)

To find: area of the parcel

Solution:

Using heron's formula,

area of triangle joining coordinates is equal to

Let

Area of triangle (parcel)

the answer is b.

step-by-step explanation:
