 <translate> Area of the outer rectangle = 21 Ã— 16 = 336 m2
Area of the inner rectangle = 17 Ã— 12 = 204 m2
Required area = (336 â€“ 204) = 132 m2
Thus, the answer is (B). <yor> Ilẹ ti awọn ita rectangle = 21 × 16 = 336 m2 Ilẹ ti awọn inu onigun mẹrin = 17 × 12 = 204 m2 Àgbègbè tí a nílò = (336 - <unk> 204) = 132 m2 Nítorí náà, ìdáhùn náà ni (B).
