Answer: A 128 square sm
Step-by-step explanation:
So the wedge consists of a square and a triangle. We need to find the area of both using 2 formulas:
A=1/2bh for triangle
A= l*w for square
Starting with the square 8*10=80 so the area of the square is 80 square cm
Now the triangle is 12*8/2 so = 48 square cm
So add the two to get 48+80= 128 Square centimeters which is choice A
