A rectangle has sides of length (2+ √18)metre and (5-4/√2)metres.
If you mean :

Express in the form a + b√2,where a and b are integers.
(i) the value of A, where A square metres is the area of the rectangle.

============================
(ii) the value of D^2, where D metres is the length of the diagonal of the rectangle.
D^2 = (2+ √18)^2 + (5-4/√2)^2 =
