A rectangle has a base of 6x+7 and a height of 7. The area of the rectangle is 133in^2.

Solve for the missing sides.

 

\(\begin{array}{|rcll|} \hline A &=& \text{base} \times \text{height} \\ A &=&(6x+7) \times 7 \quad & | \quad A =133\ \text{in}^2 \\ 133 &=&(6x+7) \times 7 \quad & | \quad :7 \\ 19 &=& 6x+7 \\ \mathbf{6x+7} & \mathbf{=} & \mathbf{19} \\ \hline \end{array}\)

 

The missing side is 19.
