    How can this be ?

    The same pieces were used to construct each of the below shapes, yet the one on the right has a greater area.
    How can this be?

    Thankyou !

    area = length * width so thats easy

    whoa whats going on? Lesley started the puzzle and allstar finishes by adding the picture!!!!

    I still can't work out where the other box comes from though as the shapes are exactly the same size in each pic ??

    what other box?

    the bits are the same in both they are just arranged differently.

    I hope im right lol

    Its got me puzzled:thinking: My oh says it is an optical illusion but I can't work out how. He says the squares are different sizes or something.

    the two boxes (two boxes with four shapes inside) have the same size shapes inside but measure different

    Right - we have printed it out and are cutting the shapes out to see if they are the same size. It has really got us puzzled!!!!!!

    its just the way they are laid out.. hmm i dont know how to explain it but its all to do with positioning off the boxes and then the fact area is lenght by width

    all the bits are the same sizes

    its hard to explain ugh

    Ok it is something to do with hypotenuses!!!!!
    We had to google it in the end.

    The problem is that the large diagonal in the 5x13 is not really a straight line. You can't really line up the hypotenuse of the 3x8 right triangles with that of the 2x5 right triangles involved in the creation of the quadrangles.
