sorry, I have to be afk for 1015 minutes, I have to attend to something important. I would much appreciate it if you can show all the working out for part a, and a diagram with the measurement of each side labelled would be helpful as well, thanks so much!

ah. hmm, alright. note that: for the top box, and the box below,dw:1359203303033:dw their areas will each be x^2 however, for the center box, let it's length be k. 2x+k=1, so k=12x. so , the length of the center box is 12x. dw:1359203362399:dw so the four boxes each have the area (12x)x
