Final answer:

To cover the windows, a total of 16.12 square meters of sun shade material is required; 0.12 m² for the two rectangular windows and 16 m² for the four square windows.

Step-by-step explanation:

To calculate the amount of sun screen (presumably a typo for sun shade) material required to cover the windows, we need to find the total area of all windows combined.

The two rectangular windows each have a length of 3 cm (which needs to be converted to meters for consistency) and a breadth of 2 m. First, we convert the length from centimeters to meters: 3 cm = 0.03 m. Now we can calculate the area of one rectangular window:

  • Area of one rectangular window = length × breadth = 0.03 m × 2 m = 0.06 m²

Since there are two such windows, we multiply by 2:

  • Total area of rectangular windows = 0.06 m² × 2 = 0.12 m²

The four square windows each have a side of 2 m, so for one square window:

  • Area of one square window = side × side = 2 m × 2 m = 4 m²

With four square windows:

  • Total area of square windows = 4 m² × 4 = 16 m²

Adding the areas of both types of windows together gives us the total amount of material needed:

  • Total sun screen material required = Total area of rectangular windows + Total area of square windows = 0.12 m² + 16 m² = 16.12 m²
