So we have actually two rectangles, we are going to find the area of the little one first that is on the top rigth. The area is 8 in^2
[tex]A\text{ = }4\text{ in }\cdot2in=8in^2[/tex]Now for the big one we have that the area is 32 in^2
[tex]A\text{ = 8 in }\cdot4in=32in^2[/tex]So the answer is 40 in^2.
