Answer 2

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 =
`s * s`

We have to find the side of the window.

Since, Area of window = 49 square feet

`s * s = 49`

`s^2 = 49`

`s = \sqrt(49)`

`s = 7` feet

Therefore, the side of the window is 7 feet long.
