Answer 5832 cm shaded area
Step by step
By dividing the large square into 4 small squares, we can find area of each small square, multiply by 4 squares, and divide by 2 to get shaded area.
A = L x W
A = 54 x 54
A = 2916
2916 x 4 smaller squares = 11664
Divide by 2 because each small square is 1/2 shaded
11664 / 2 = 5832 shaded area
