Final answer:
The length of the window is 85 cm.
Step-by-step explanation:
To find the length of the window, we can use the formula for the area of a rectangle, which is length multiplied by width. Given that the area of the window is 4420 cm² and the width is 52 cm, we can solve for the length:
Length x Width = Area
Length x 52 cm = 4420 cm²
Length = 4420 cm² / 52 cm
Length = 85 cm
Therefore, the length of the window is 85 cm.
