A new homeowner buys 120 square feet of carpet for a room in her new house. If the room is square, what is the length of each side of the room? (Recall that the area of a square is calculated by 2003-04-02-00-00_files/i0170000.jpg, where l is the length of one side.)

Respuesta :

So we can solve by,

[tex] {x}^{2} = 120[/tex]

Simply take the root of 120 and get,

[tex]x = 2 \sqrt{30} [/tex]

Or 2 × the square root of 30.

[tex]2 \sqrt{30 } ≈10.94446[/tex]
