Answer:

24 m^2

Step-by-step explanation:

There are two areas to consider here:  first, the area of the wall, and second, the area of the window.  We answer this question by finding these two areas and subtracting the area of the window from the area of the wall.

Wall area:  (4 m)(7 m) = 28 m^2

Window area:  (2 m)(2 m) = 4 m^2

Net area of wall, to be covered in brick:

28 m^2 - 4 m^2 = 24 m^2
