The area of the shaded region can be gotten by multiplying the area of the circle by the subtended angle of the sector.

Well, darling, if you shaded all but three eighths of the rectangle, then the shaded area is 5/8 of the total rectangle. To find the percentage of the rectangle that is not shaded, you subtract the shaded area from 100%. So, 100% - 62.5% (5/8 as a percentage) = 37.5%. Voilà, 37.5% of the rectangle is not shaded.
A formula is needed to find the area of a parallelogram. It is a very simple formula which notates Area = base x height.

The area of the shaded region can be gotten by multiplying the area of the circle by the subtended angle of the sector.
find the area of the shaded sector 12cm and 24°
The formula to find the surface area of a parallelogram is Base*Height.
Either directly or by finding the area of the whole and subtracting the area of the non-shaded part.
It depends on what the shaded and non-shaded parts look like!
To find the area of a parallelogram, multiply the base by the height.
Well, honey, the area of a shaded region is simply the difference between the total area and the area of the unshaded parts. Just calculate the area of the entire shape and subtract the areas of any parts that aren't shaded. It's basic math, darling, nothing to lose sleep over.
You will need to divide the shaded area into smaller parts, such as triangles or rectangles, or find the length of sides of these polygons.

To find the area of a parallelogram, multiply the length of the base by the height. The height should be perpendicular to the base.
