Perimeter = 36 cm

heron’s formula: area =

what is the area of an equilateral triangle that has a perimeter of 36 centimeters? round to the nearest square centimeter.

15 square centimeters
62 square centimeters
72 square centimeters
705 square centimeters

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.  

multiply length by height. multiply the length by the height, and then double the product. work out 10 x 10 results = 100 square inches, then work out 100 x 2 = 200. the answer is 200 square inches.
