Question

PLEASE HELP FAST MAKE YOU BRANLEYEST! 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 (−8, 2), (−8, −5), (8, 2), and (8, −5). What is the area, in square inches, of the painted face of the brick?

24 in2
46 in2
56 in2
112 in2

Answer 1

112 in²

Explanation:

width of the brick = (2 - - 5) = 7 this is the distance between the vertices in the y direction

length of the brick = (8 - -8) = 16 this is the distance between the vertices in the x direction

Area = length x width= 16 x 7 = 112 in²

Note: it helps if you graph these points, then you can see the problem better
