x and y, dimensions of the rectangle;
base of the isosceles right triangle lies along x; the each leg of the isosceles triangle (the two congruent ones) is .

AREA:

PERIMETER, p:

-
(Set derivative equal to 0 to solve for x dimension for the minimum perimeter p).
-
This is not the completed solution.
