Determine the area of the shaded region (grey) in the quadratic form. Hint: Shaded area = (gray rectangle area) – (white rectangle area)

The area of shaded region is:

Step-by-step explanation:

We can see in the diagram that

The area of rectangle is given by:

Area = Length * width

Now for gray rectangle

For White Rectangle:

Now,

The area of shaded region will be calculated by subtracting the area of white triangle from the gray triangle.

Hence,

The area of shaded region is:
