The skepticism about the empire of Ghana and the accounts for it is nothing weird because the majority of what is written about it is from two people from the same place, that had totally different views and interpretations on the things, and came from different culture.
Very often in the historical text, the people that wrote something have been very subjective, not objective. Thus the writings of these two Arab geographers can be very misleading, as they described what they saw with their own eyes, but also with using their own perception. That has proven numerous times to give very inaccurate depictions of a society and culture, like the depictions of the Romans for the Celts, or of the Greeks for the Scythian female warriors that they named Amazons.

Answer:
Perimiter: 14.2
Area: 11.7
Explanation:
To find the perimiter, you have to multiply the length: 4.5 x 2 = 9....Then multiply the width: 2.6 x 2 = 5.2....Lastly, add 9 with 5.2. This will give you the perimiter of 14.2.
To find the area, you have to multiply Length(4.5) x (2.6)Width which will get you the area of 11.7.
Hope that helps :)
