ABGF is a square with half the perimeter of square ACDE. GD = 4in. Find the area of the shaded region.

Please help me work this problem out I am stuck.
It's a square and in the top right corner there in another square inside it that is 1/4 the size of the big one. From that corner there is a diagonal line going to the other corner saying GD=4in
The shaded area is the 3/4 that are not part of the little 1/4 square
Please help me

Someone told me that the answer is 24, which is correct, but I'm not sure how they got it :(, but hopefully that at least helps a little.
