Answer:
36 in.
Step-by-step explanation:
find the area of the rectangle and triangle first
area of rectangle = length x height
aR = (6 + 6) x 5
aR = 12 x 5
aR = 60
area of triangle = base x height x 1/2
aT = (6 + 6) x 4 x 1/2
aT = 12 x 4 x 1/2
aT = 24
now, to find the area of the shaded area subtract the triangle from the rectangle
area = rectangle - triangle
a = 60 - 24
a = 36
