Explanation:

Step1: Aplicar fórmula área rectángulo

1. $(4.5\ m)(2\ m)=9\ m^{2}$
2. $(9\ cm)(7\ cm)=63\ cm^{2}$
3. $(22\ m)(40\ m)=880\ m^{2}$
4. $(10\ mm)(11\ mm)=110\ mm^{2}$
5. $(2.5\ cm)(6.5\ cm)=16.25\ cm^{2}$
6. $(15\ mm)(25\ mm)=375\ mm^{2}$
7. $48\ m^{2}\div6\ m = 8\ m$
8. $(12\ cm)(18\ cm)=216\ cm^{2}$
9. $1400\ mm^{2}\div14\ mm = 100\ mm$
10. $(120\ m)(17\ m)=2040\ m^{2}$
11. $(8.5\ mm)(3.5\ mm)=29.75\ mm^{2}$
12. $(35\ m)(30\ m)=1050\ m^{2}$
13. $56\ cm^{2}\div4\ cm = 14\ cm$
14. $(20\ cm)(20\ cm)=400\ cm^{2}$
15. $140\ m^{2}\div70\ m = 2\ m$

Answer:

1. $9\ m^{2}$
2. $63\ cm^{2}$
3. $880\ m^{2}$
4. $110\ mm^{2}$
5. $16.25\ cm^{2}$
6. $375\ mm^{2}$
7. $8\ m$
8. $216\ cm^{2}$
9. $100\ mm$
10. $2040\ m^{2}$
11. $29.75\ mm^{2}$
12. $1050\ m^{2}$
13. $14\ cm$
14. $400\ cm^{2}$
15. $2\ m$
