I've got psychometric test coming up and I've just realized that in the numeracy reasoning section, I will most likely have a question or two about areas and perimeters, I've got one example question which might give you an idea of the difficulty I will be faced with (not much to you I doubt) it will be multiple choice but I guess knowing the answer for sure is best.
If the perimeter of the square is 20cm, then the area of the square, in square centimetres is?
So could you tell me how to work this out?
Also, give me a short list of things I should know about squares, perimeters, shape and all that jazz. Times like these I really wish I studied in School.
Oh and I'm sorry, this is like my 4th or so post, if you guys have a problem with this like if it is spam or something please tell me but your help has been really great drink water so far.
