1. 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)

Me too. Seems a bit of a strange question. Is it a-level or gcse or something else?
