Unshaded area = area of triangle. The pink line is the base, and the green line is the height of the triangle.
The green line is made up of the blue line and the yellow line.
Hence, you know the lengths of both the base and height of the triangle. Just find the area of the triangle next.

Area of shaded area = Area of blue square + Area of pink square - Area of unshaded triangle (marked in green)
