The answer is B for sure!!!

Answer: B. [tex]38\ in^2[/tex]

Step-by-step explanation:

Area of a rectangle with dimension " l by w" is given by :-

[tex]A_r=l\times w[/tex]

Area of square with dimension  "a by a" is given by :_

[tex]A_s=(a)^2[/tex]

Now Using (1), Area of rectangle with dimension  9-inch by 6-inch will be :-

[tex]A_r=9\times 9=54\ in^2[/tex]                  

Using  (2),  Area of square with dimension 4-inch by 4-inch  will be :-

[tex]A_s=4^2=16\ in^2[/tex]          

Now, the required area = [tex]A_r-A_s=54-16=38\ in^2[/tex]

Hence, B is the correct option.
