    Hi, can you help solve this please?

    A rectangular garden of width w metres and length (w + 4)metres

    The length of the garden's diagonal is d metres, so

    d(squared)= 2w(squared) +8w + 16 ........after working out pythagora's

    Given also that d must be at least twice as big as w,
    show thar the maximum value of w can be expressed in the form
    (a = b(square root)3)
