6x + 4 = x - 11
- 6x -6x

4 = -5x - 11
+11 +11

15 = -5x

x = -3

$6x+4=x-11\ \ \ | subtract \ x\\\\
5x+4=-11\ \ \ \ | subtract\ 4\\\\
5x=-15\ \ \ | divide\ by\ 5\\\\
x=-3$

$\frak {\pink{Let}}\begin{cases} \sf{\red{Breadth \: be \: x}}\\ \sf{\orange{The \: Length = x + 9}}\end{cases} \\$

$:\implies \sf {x}^{2} + 9x - 360 = 0\\ \\ \\$

Answer:

$\huge\boxed{Answer\hookleftarrow}$

From the figure we can see that, $\large\bold{3x°}$ & $\large\bold{x + 30°}$ are vertically opposite angles.

⎆ <u>Vertically opposite angles are equal to each other.</u>

<u>____________________</u>

So, equation ⇻ $\large\bold{3x° = x + 30°}$

____________________

Value of x will be :-

$3x° = x + 30° \\ 3x - x = 30 \\ 2x = 30 \\ x = \frac{30}{2} \\ x = 15$
