Investigation into Equable Rectangles Firstly, I will work out the equable 1:2 rectangle... (2:1) 2(a + 2a) = a * 2a - Next Step is to expand the brackets. 2a + 4a = a * 2a - Now I have to simplify.

2. ## Perfect Shapes

It seems reasonable to assume therefore that a perfect 5 by (something between 3 and 4) rectangle exists. Notice also that as we progress down the Perimeter - Area column the difference between the area and the perimeter is getting larger, this seems to suggest that another perfect shape will not be found.
