求长方形的面积(S)
①$a = 19\text{dm}$ $b = 5\text{dm}$
②$a = 13\text{cm}$ $b = 8\text{cm}$
③$a = 24\text{m}$ $b = 16\text{m}$
④$a = 14\text{m}$ $b = 11\text{m}$
⑤$a = 15\text{m}$ $b = 8\text{m}$
⑥$a = 12\text{cm}$ $b = 10\text{cm}$
⑦$a = 20\text{m}$ $b = 15\text{m}$
⑧$a = 40\text{cm}$ $b = 25\text{cm}$
⑨$a = 33\text{m}$ $b = 20\text{m}$
⑩$a = 16\text{cm}$ $b = 8\text{cm}$

答案： $95dm^{2}$ $104cm^{2}$ $384m^{2}$ $154m^{2}$ $120m^{2}$ $120cm^{2}$ $300m^{2}$ $1000cm^{2}$ $660m^{2}$ $128cm^{2}$
