Matt's den is 10 feet longer than it is wide. If the dents area is 231 square feet, what are the dimensions of the room?
sashaice [31]

Answer:

21\: \mathrm{feet\: by}\:  11 \: \mathrm{feet}

Step-by-step explanation:

(Assuming the den is a rectangle)

Let x be the length of the den. Because the length is 10 feet longer than the width, the width of the den can be represented as x-10.

The area of a rectangle is given as l\cdot w, therefore we can form the following equation:

x(x-10)=231

Expanding this, we have:

x^2-10x=231, \\\\x^2-10x-231=0

This factors into (x-21)(x+11)=0, therefore x=21, \: -11.

Because -11 is extraneous, the length of the den is 21 feet and the width is 21-10=11. Thus, the dimensions of the den are \fbox{$21\: \mathrm{feet\: by}\:  11 \: \mathrm{feet}$}.
