Tent base 2.3 by 4.2 metres what is the ground seface total

You multiply both numbers:

2.3 x 4.2

The answer is the product of the two numbers:

2.3 x 4.2 = 9.66

9.66

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.
