Answer 1

45 +9 =54 высота, 9 + 54= 63 периметр

Answer 2

Calculation of Window Perimeter

To find the perimeter of a window, we need to know the width and height of the window frame. In this case, the width of the window frame is 9 dm (decimeters), and the height is 45 cm (centimeters) greater than the width.

Let's convert the height to decimeters to ensure consistent units. Since 1 dm is equal to 10 cm, the height in decimeters would be 45 cm / 10 = 4.5 dm.

Now, we can calculate the perimeter of the window frame by adding up the lengths of all four sides.

The formula for the perimeter of a rectangle is:

Perimeter = 2 * (Width + Height)

Substituting the given values:

Perimeter = 2 * (9 dm + 4.5 dm)

Calculating the expression inside the parentheses:

Perimeter = 2 * (13.5 dm)

And finally, calculating the perimeter:

Perimeter = 27 dm

Therefore, the perimeter of the window frame is 27 decimeters.
