Calculate the area and perimeter for this parallelogram.

Step-by-step explanation:

Perimeter = 29.4 ft

Area = 45.9 ft²

Step-by-step explanation:

Perimeter = 2(a+c)

= 2(5.7+9) = 2(14.7) = 29.4 ft

Area = h×c

= 5.1×9 = 45.9 ft²

the last choice

step-by-step explanation:

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.
