A rectangle has an area A, and the length L is k longer than the width w. What is L, or find a formula for L.

Unknown variables are w and L.

and ; using this formula for L, .
Returning to the area relationship,



-
The numbers and , so the usage of signs for the solution for L are unmistakable. Use the solution for the general solution to a quadratic equation with the positive square root form.
-



You can make the substitutions of k=7 and A=198 and compute L.

Let width's measurement be W

Then length = W + 7

Therefore, W(W + 7) = 198



Solve for W, or width, discarding the negative (< 0) value

Add 7 to the value of W, or width to determine value of length

You can do the check!! 



If you need a complete and detailed solution, let me know!!
