Question

Builders are covering a wall that is 4 meters tall and 7 meters wide with bricks. They will cover the entire wall except for a square window that measures 2 meters on all sides. How many square meters of the wall will be covered in bricks

Answer 1

24 m^2

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
