To find the area of a rectangle, we multiply the length by the width. In this case, the length is -2x+12 and the width is 4x-3.
Therefore, the expression that represents the area of the classroom in square feet is:
(-2x+12)(4x-3)
Multiplying this expression would give us the area in square feet. However, none of the given options match this expression.
The diagram shows the floor plan of a classroom. All dimensions are given in feet.

Apologies for the confusion. Let's try again.
The area of a rectangle is calculated by multiplying its length by its width. In this case, the length of the rectangle is -2x+12 and the width is 4x-3.
Therefore, the expression that represents the area of the classroom in square feet is:
(-2x+12)(4x-3)
Expanding this expression gives us:
-8x^2 + 42x - 36
Hence, the correct option is:
-8x^2 + 42x - 36
