The Area of Shaded region is equal to the difference in Area of rectangle and Area of triangle .
let's solve for area of rectangle :



Now, Area of Triangle :



So, the area of the shaded region in terms of x :


And since, Area of Shaded region = 44 cm²
By equating the area, we get

Value of x = 2

Correct Answer: Option AThe next step in simplification will be to convert the squared term so that it no longer contains a square.
So, we are to simplify the term

Using the half-angle identity we can write:

Using this value, the equation becomes:
Therefore, option A is the correct answer.
