Answer:
A. 99 cm^2
Step-by-step explanation:
The entire area including the non shaded part is equivalent to
15 x 9 cm
the entire area is 135 cm^2
The area of the square is equivalent to 6 x 6
the non shaded area is 36 cm^2
To find the shaded area you subtract the non shaded area from the shaded area
135-36
You are left with 99 cm^2 as the area of the shaded part of the figure.
