A student is painting a brick for his teacher to use as a doorstop in the classroom. He is only painting the front of the brick. The vertices of the face are (−6, 2), (−6, −7), (6, 2), and (6, −7). What is the area, in square inches, of the painted face of the brick?

Question

144 in2
108 in2
72 in2
42 in2

Answer 1

The area of a rectangle is found by multiplying its length by its width. In this case, the length of the rectangle is 12 units (6 - (-6)) and the width is 9 units (2 - (-7)).

Therefore, the area of the painted face of the brick is 12 units * 9 units = 108 square units.

So, the correct answer is 108 in2.
