Answer:
96 cm^2
Step-by-step explanation:
this shape is easiest to find the area of by finding the area of a rectangle of this size and then subtracting the small rectangle cut out
the bottom edge is 12cm long, (3cm + 6cm + 3cm)
if the figure were a rectangle without a notch cut into it the equation would be
12 cm x 9cm = 108 cm^2
in this problem we also calculate the area of the notch rectangle, and subtract that from the area of the larger rectangle
(12 cm x 9cm) - (2cm x 6cm) =
108cm - 12cm = 96 cm^2
