The length of a diagonal of a square is 18√2 millimeters. Find the perimeter of the square.

Step-by-step explanation:

let edge of square=x

x²+x²=(18√2)²

2x²=2×18²

x²=18²

x=18

edge=18 mm

perimeter=4×x=4×18=72 mm

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.
