What is the area of a polygon with vertices (3, 2), (1, -2), and (-3, 5)? Round to the nearest whole number, if necessary.

i got 10.28 but that rounds up to 10.3

the answer is; biodiversity resulting from few ancestors

adaptive radiation occurs when a population is subjected to a large natural environment with spatial ecological variations. the parts of the population in the different ecologies begin to adapt to their local environments. due to non-random mating across the large populations, this causes the different populations from the large population to speciate within their local environments. they, therefore, diverge to different species sharing a common ancestor.
