    The perimeter of the square is 330/2 = 165 cm since half of the sides
    are "interior" to the square. so the side length is 165/4 = 41.25cm
    and the area is 41.25*41.25 = 1701.563 sq cm


    Correction, the center rectangles will only have one external edge, so
    if rectangle is a * b then we get

    2a = 3b
    12a + 12b = 330

    solving for b..

    b = 7.666cm , a = 11.5 cm

    square side is 3b, oe 23 cm

    square area is 23*23 = 529 sq cm

    Is that your funky green machine?
    I know that is what I mean, you take a first impression and start running without actually reading it and processing it sometimes.

    Use to be mine, sold it to a 15 year old two months ago to make more space in the shed for my woodworking and to reduce the hobbies/toys - first born is on the way.

    It's a shame when you don't have room in your life for all your loves. Both time and space are limited, come on science.

    for it it be square 2a must = 3b,

    adding up the edges of all the rectangles 2*6*a + 2*6*b = 330

    so 2*6*3b + 2*6*b = 330
    b = 7.666.

    so side of square must be 23 cm and area is 23*23 = 529 sq cm

    More caffiene.. need more caffiene...

    I think Arty has done a runner. Possible reasons:
    • Does not have the answer
    • Typo in the first place meant the question is wrong
    • Is busy copying the the possible anwers into his assignment (he'll get extra marks for Ray's anwer)
    • Just likes to give us all the
    Just spent five minutes looking for that last emoticon, never looked at them all before, how's this one

    QED

    Ray, its late and I could be wrong but if you combine these two equations, b = 11

    so is it irish coffee we are on tonight?????

    your approach assumes he wants rectangles arranged 3 x 2 but you can do 6 on top of each other too so I am not sure what spirit wants?

    Oh well back to my coffee!!!!!!!

    No, and the house is smaller than the shed, (which is too small anyway). if that helps.
