Respuesta :
It is given that the area of window = 49 square feet
Since, window is in the shape of square.
Area of square with side 's' is given by the formula = [tex]s \times s[/tex]
We have to find the side of the window.
Since, Area of window = 49 square feet
[tex]s \times s = 49[/tex]
[tex]s^2 = 49[/tex]
[tex]s = \sqrt(49)[/tex]
[tex]s = 7[/tex] feet
Therefore, the side of the window is 7 feet long.
