When a rectangular paddock is divided into four paddocks by erected fences parallel to the shorter sides, the total length of fencing material for the four paddocks (including the existing fences) is 1760m. If the dividing fences had been erected parallel to the longer sides the total length of fencing for the four paddocks (including the existing fences) would have been 2090m. Find the length and width of the original paddock.

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.
