Let's solve the problem step by step, filling in the equations and converting the units as required.

### (1) Plotësoni barazimet.

a. $$ 1 \mathrm{~m}^{2} = $$ $$ 10,000 \mathrm{~cm}^{2} $$  
   (Since $$ 1 \mathrm{~m} = 100 \mathrm{~cm} $$, therefore $$ 1 \mathrm{~m}^{2} = (100 \mathrm{~cm})^2 = 10,000 \mathrm{~cm}^{2} $$)

b. $$ 1 \mathrm{~cm}^{2} = $$ $$ 100 \mathrm{~mm}^{2} $$  
   (Since $$ 1 \mathrm{~cm} = 10 \mathrm{~mm} $$, therefore $$ 1 \mathrm{~cm}^{2} = (10 \mathrm{~mm})^2 = 100 \mathrm{~mm}^{2} $$)

c. $$ 1 \mathrm{~km}^{2} = $$ $$ 1,000,000 \mathrm{~m}^{2} $$  
   (Since $$ 1 \mathrm{~km} = 1,000 \mathrm{~m} $$, therefore $$ 1 \mathrm{~km}^{2} = (1,000 \mathrm{~m})^2 = 1,000,000 \mathrm{~m}^{2} $$)

d. $$ 1 \mathrm{~ha} = $$ $$ 10,000 \mathrm{~m}^{2} $$  
   (1 hectare is defined as $$ 10,000 \mathrm{~m}^{2} $$)

### (2) Ktheni në $$ \mathrm{cm}^{2} $$.

a. $$ 3 \mathrm{~m}^{2} = 3 	imes 10,000 \mathrm{~cm}^{2} = 30,000 \mathrm{~cm}^{2} $$

b. $$ 2.8 \mathrm{~m}^{2} = 2.8 	imes 10,000 \mathrm{~cm}^{2} = 28,000 \mathrm{~cm}^{2} $$

c. $$ 400 \mathrm{~mm}^{2} = \frac{400}{100} \mathrm{~cm}^{2} = 4 \mathrm{~cm}^{2} $$

d. $$ 1000 \mathrm{~mm}^{2} = \frac{1000}{100} \mathrm{~cm}^{2} = 10 \mathrm{~cm}^{2} $$

e. $$ 0.5 \mathrm{~m}^{2} = 0.5 	imes 10,000 \mathrm{~cm}^{2} = 5,000 \mathrm{~cm}^{2} $$

f. $$ 20 \mathrm{~mm}^{2} = \frac{20}{100} \mathrm{~cm}^{2} = 0.2 \mathrm{~cm}^{2} $$

g. $$ 100 \mathrm{~m}^{2} = 100 	imes 10,000 \mathrm{~cm}^{2} = 1,000,000 \mathrm{~cm}^{2} $$

h. $$ 32 \mathrm{~mm}^{2} = \frac{32}{100} \mathrm{~cm}^{2} = 0.32 \mathrm{~cm}^{2} $$

### (3) Ktheni në $$ \mathrm{mm}^{2} $$.

a. $$ 4 \mathrm{~cm}^{2} = 4 	imes 100 \mathrm{~mm}^{2} = 400 \mathrm{~mm}^{2} $$

b. $$ 7.5 \mathrm{~cm}^{2} = 7.5 	imes 100 \mathrm{~mm}^{2} = 750 \mathrm{~mm}^{2} $$

c. $$ 2 \mathrm{~m}^{2} = 2 	imes 10,000 \mathrm{~cm}^{2} = 20,000 \mathrm{~cm}^{2} = 20,000 	imes 100 \mathrm{~mm}^{2} = 2,000,000 \mathrm{~mm}^{2} $$

d. $$ 6.8 \mathrm{~m}^{2} = 6.8 	imes 10,000 \mathrm{~cm}^{2} = 68,000 \mathrm{~cm}^{2} = 68,000 	imes 100 \mathrm{~mm}^{2} = 6,800,000 \mathrm{~mm}^{2} $$

### (4) Ktheni në $$ \mathrm{m}^{2} $$.

a. $$ 3 \mathrm{~km}^{2} = 3 	imes 1,000,000 \mathrm{~m}^{2} = 3,000,000 \mathrm{~m}^{2} $$

b. $$ 8000 \mathrm{~cm}^{2} = \frac{8000}{10,000} \mathrm{~m}^{2} = 0.8 \mathrm{~m}^{2} $$

c. $$ 9000000 \mathrm{~mm}^{2} = \frac{9000000}{1,000,000} \mathrm{~m}^{2} = 9 \mathrm{~m}^{2} $$

d. $$ 7.2 \mathrm{~km}^{2} = 7.2 	imes 1,000,000 \mathrm{~m}^{2} = 7,200,000 \mathrm{~m}^{2} $$

This completes the conversions and fills in the equations as required.
Here are the conversions and solutions: 1. **Plotësoni barazimet:** - $$ 1 \mathrm{~m}^{2} = 10,000 \mathrm{~cm}^{2} $$ - $$ 1 \mathrm{~cm}^{2} = 100 \mathrm{~mm}^{2} $$ - $$ 1 \mathrm{~km}^{2} = 1,000,000 \mathrm{~m}^{2} $$ - $$ 1 \mathrm{~ha} = 10,000 \mathrm{~m}^{2} $$ 2. **Ktheni në $$ \mathrm{cm}^{2} $$:** - $$ 3 \mathrm{~m}^{2} = 30,000 \mathrm{~cm}^{2} $$ - $$ 2.8 \mathrm{~m}^{2} = 28,000 \mathrm{~cm}^{2} $$ - $$ 400 \mathrm{~mm}^{2} = 4 \mathrm{~cm}^{2} $$ - $$ 1000 \mathrm{~mm}^{2} = 10 \mathrm{~cm}^{2} $$ - $$ 0.5 \mathrm{~m}^{2} = 5,000 \mathrm{~cm}^{2} $$ - $$ 20 \mathrm{~mm}^{2} = 0.2 \mathrm{~cm}^{2} $$ - $$ 100 \mathrm{~m}^{2} = 1,000,000 \mathrm{~cm}^{2} $$ - $$ 32 \mathrm{~mm}^{2} = 0.32 \mathrm{~cm}^{2} $$ 3. **Ktheni në $$ \mathrm{mm}^{2} $$:** - $$ 4 \mathrm{~cm}^{2} = 400 \mathrm{~mm}^{2} $$ - $$ 7.5 \mathrm{~cm}^{2} = 750 \mathrm{~mm}^{2} $$ - $$ 2 \mathrm{~m}^{2} = 2,000,000 \mathrm{~mm}^{2} $$ - $$ 6.8 \mathrm{~m}^{2} = 6,800,000 \mathrm{~mm}^{2} $$ 4. **Ktheni në $$ \mathrm{m}^{2} $$:** - $$ 3 \mathrm{~km}^{2} = 3,000,000 \mathrm{~m}^{2} $$ - $$ 8000 \mathrm{~cm}^{2} = 0.8 \mathrm{~m}^{2} $$ - $$ 9000000 \mathrm{~mm}^{2} = 9 \mathrm{~m}^{2} $$ - $$ 7.2 \mathrm{~km}^{2} = 7,200,000 \mathrm{~m}^{2} $$
