~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
The shape in the figure is a square with four cut triangles.
The side of the square is 1 + 1 + 1 = 3 units, so its area is 9 square units.
Of four cut triangles, each of them is a right angled isosceles triangle with
leg size of 1 unit, so the area of each such triangle is 1/2.
Thus the area of the shape under the question is 9 - 4 * (1/2) = 9 - 2 = 7 square units.
ANSWER. The area of the shape under the question is 7 square units.
