Find the dimensions of the rectangle of maximum area that can be constructed with a perimeter of 44cm.
I tried using Google for help, but common methods used were derivatives which I haven't been taught yet. I'm a little lost, so an explanation would be helpful! :)
It can be shown that the area will be maximized when each side of the rectangle is equal to the perimeter / 4....in essence the rectangle will be a square
So...each side will = 44/ 4 = 11 cm
And the maximum area is 11^2 = 121 cm^2
