The width of a rectangle is 2 1/2 centimeters. The length of the rectangle is twice it’s width. What is the area of the rectangle?

A 11 1/4 square centimeters
B 12 1/2 square centimeters
C 14 square centimeters
D 15 square centimeters

A. 11 1/4

Step-by-step explanation:

The width of the rectangle is 2 1/2.

The length of the rectangle is twice its width.

So that means the length is:

2 1/2*2= 4 1/2 since the length is twice the width

Area of rectangle= length*width

= 4 1/2*2 1/2= 11 1/4

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.
