Given that the four triangles are congruent, the total area of the figure is the area of the square plus 4 times the area of one triangle.

Recall that the area of a triangle is given by the formula:


A=(base*height)/(2).

Therefore, the area of one of the triangles is:


A_(triangle)=(8in*4in)/(2).

Simplifying the above result, we get:


A_(triangle)=16in^2.

Now, the area of a square is given by:


A=side*side.

Therefore, the area of the square is:


A_(square)=4in*4in.

Simplifying the above result, we get:


A_(square)=16in^2.

Finally, we get that:


A_(total)=4A_(triangle)+A_(square)=4*16in^2+16in^2=80in^2.

Answer:


80in^2.
