SOLUTION

Step1:

hence from the diagram above, the dimension of the rug is

[tex]\begin{gathered} 34-2x\text{ and } \\ 24-2x \end{gathered}[/tex]

Since we have area of the rug,

then we have

[tex](34-2x)(24-2x)=704[/tex]

We now solve the equation above quadratically

[tex]\begin{gathered} (34-2x)(24-2x)=704 \\ \text{expand the parenthesis } \\ 16-116x+4x^2=704 \\ \text{subtract 704 from both sides } \\ 816-116x+4x^2-704=704-704 \end{gathered}[/tex]

Then we have

[tex]4x^2-116x+112=0[/tex]

Solve using factor method we obtain

[tex]\begin{gathered} \text{Divide through by 4} \\ x^2-29x+28=0 \\ x^2-28x-x+28=0 \\ x(x-28)-1(x-28)=0 \\ (x-28)(x-1)=0 \end{gathered}[/tex]

Equating each factor to zero we have

[tex]\begin{gathered} x-28=0,x-1=0 \\ x=28,1 \end{gathered}[/tex]

Since x can not be 28, the value of x is 1

The Dimension of the rug becomes

[tex]\begin{gathered} 34-2x=34-2(1)=32 \\ \text{and } \\ 24-2x=24-2(1)=22 \end{gathered}[/tex]

Hence the dimension of the rug is 32 ft by 22ft (22,32)
