Answer:
x = 7
Step-by-step explanation:
Let's join A & C . If points A ,B & C are collinear , then definitely B point's gonna lie on line segment AC .
So , AC = AB + BC
In the question , length of AC = 3x + 3 , length of AB = 2x - 1 ( or -1 + 2x)
& length of BC = 11.
We know that AC = AB + BC . So putting the given values here :-

Solving this linear eqn. gives

24, because area means to multipy and it gives 6 ins. and 4 ins. so 6x4 is 24. Hope I was helpful.
