Mr.Webster is buying carpet for an exercise room in his basement. The room will have an area of 230 square feet. The width of the room is 12 1/2 feet.What is the length?

Respuesta :

The lenght is 18 2/5 feet

Answer:

Length = [tex]18\frac{2}{5}[/tex] feet

Step-by-step explanation:

Simplify the fraction of the width:

[tex]12\frac{1}{2}=\frac{25}{2}[/tex]

Using the formula for Area:

[tex]A=l*w\\l=\frac{A}{w}[/tex]

Substituting the known values:

[tex]l=\frac{230}{\frac{25}{2}}\\l=230*\frac{2}{25}\\l=\frac{460}{25}\\l=\frac{92}{5}\\l=18\frac{2}{5}[/tex]
