Help, picture attached.
I am having trouble with part a but I should be able to figure out the rest.
have you found the length of the center box?
nope, I am really confused.
sorry, I have to be afk for 10-15 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=1-2x. so , the length of the center box is 1-2x. |dw:1359203362399:dw| so the four boxes each have the area (1-2x)x
