Area of Composite Figures
Composite figures are shapes composed of two or more simpler shapes combined to form a new, more complex shape. To calculate the area of a composite figure, we need to determine the area of each individual shape and then add them together.
For example, a rectangle with a semicircle attached to one side is a composite figure. The area of the rectangle can be calculated using the formula length x width, while the area of the semicircle can be calculated using the formula πr², where r is the radius of the semicircle.
