$\huge \bold{solution}$

⤵⤵⤵

SIDE OF THE BIGGER SQUARE = 18 cm

FORMULA FOR AREA OF THE SQUARE = LENGTH × BREADTH

=> 18 CM × 18CM

=> 324 CM ²

CORNERS OF THE SMALLER SQUARE = 2 CM AND 5 CM

18 - 2 - 5 = 11 cm

=> FORMULA FOR AREA OF THE SQUARE = LENGTH × BREADTH

=> 11 CM × 11 CM

=> 121 CM ²

⬇⬇⬇

AREA OF THE UNSHADED PART = 324 CM ² - 121 CM ²

=> 203 CM ²

$\boxed{answer = 203 \: cm^{2}}$
