To find the area of the blue region, we need to subtract the area of the small square from the area of the large square.

Area of large square = 8 cm x 8 cm = 64 square cm

Area of small square = 3.2 cm x 3.2 cm = 10.24 square cm

Area of blue region = 64 square cm - 10.24 square cm = 53.76 square cm

Therefore, the best choice is B) 10.24 square centimeters.
