In a previous article I described how to fill a shape with any percentage of colour. In the article I filled half a circle with the colour black. Let's attempt the same using the Merge Shapes function.
Draw you shape and apply a No fill by right clicking and choosing Format Shape.
Duplicate that shape. You can use Ctrl+D to diplicate it quickly.
Drag the duplicate away to work more freely. Draw a rectangle covering the duplicate shape in the proportion you need.
Select the duplicate shape and then the rectangle.
Click the Shape Format tab and select the Merge shapes button in the Insert shapes group.
Now apply the Fragment option.
Now eliminate the superfluous parts by selecting and deleting them.
Apply a fill colour (black) as needed by choosing the Solid radio button in the Format Shape task pane and drag the part you need on top of the original shape.
