  1. w(3w-10) = 8
    4*2 = 8
    so, the width is 4 ft and the length is 3*4-10 = 2 (strange that the length is less than the width, but oh well...)
    Now, as it is very easy to find, using google,
    1 meter is 3.28 feet, so 1 ft is 1/3.28 meter

    So, the width is 4/3.28 = 1.22 meters

    Not hard, if you break it into small pieces.
