What is the area of the polygon defined by the points a(12, 20), b(20, 20), c(20, 8), and d(12, 8)? a 96 square units b 132 square units c 24 square units d 48 square units

  a.  96 square units

Step-by-step explanation:

The figure is a rectangle with width AB = (20-12) = 8 units and height BC = (20-8) = 12 units.

The area of the rectangle is (8 units)×(12 units) = 96 square units.

look at the picture.

y-intercept for the function on a picture is 4 → point (0, 4).

y-intercept for the function

is for x = 0. substitute:

y-intercept is 8 → point (0, 8).
