There are different formulae for different shapes.
Try to break down the composite firgure into components that you can add together (or subtract one from the other). An annulus, for example, is a big circle minus a smaller circle. Areas of squares, triangles, trapeziums, circles, semicircles and the process described anove will answer most high school questions.
For more complex figures you may need to look elsewhere. Copy the shape onto a lamina of uniform density. Cut out the shape and find its mass. Also find the mass of a unit square of the lamina. Then area of composite shape = size of unit shape*mass of composite shaped lamina/mass of unit shape.

How do you find the surface are of a composite figure?
Add the areas of all shapes or all faces that make up the composite figure.
How do you find the perimeter of a composite figure?
You have to break the figure into smaller parts.Then add all the sides together.
What is definition for composite figure?
A composite figure is a figure that is made up of two or more geometric figures.
How can you find the area of a composite figures trapezoid with a triangle?
To find the area of a composite figure consisting of a trapezoid and a triangle, you would first calculate the area of the trapezoid using the formula A = (1/2)h(b1 + b2), where h is the height of the trapezoid and b1 and b2 are the lengths of the two parallel bases. Then, you would calculate the area of the triangle using the formula A = (1/2)bh, where b is the base of the triangle and h is the height. Finally, you would add the areas of the trapezoid and the triangle together to find the total area of the composite figure.
Area of quadrilateral?
To find the area of a quadrilateral, multiply the length and width of the figure. The product will give you the area of the figure.
