A figure (or shape) that can be divided into more than one of the basic figures is said to be a composite figure (or shape). The area of a composite figure is calculated by dividing the composite figure into basic figures and then using the relevant area formula for each basic figure.

Split the figure into smaller shapes that can have their areas easily calculated and add them all together.

Example: Find the area of the hexagon A..F below:

. . . . . . . . . . . . .

.A ------ B . . . .

. . | . . . | . . . . . .

. . | . . . | . . . . . .

. . | . . . | C . . . .

. . | . . . ----- .D .

. . | . . . . . . | . . .

. . | . . . . . . | . . .

.F ---------- E . .

. . . . . . X . . . . . .

. . . . . . . . . . . . . .

By joining vertex C to point X so that length XE is the same as side CD will split the hexagon into 2 rectangles (ABXF and CDEX) which can have their areas calculated and added together to give the area of the hexagon A..F.
