To find the area of the composite figure, we need to calculate the area of each individual rectangle and then add them together.
The area of the larger rectangle is calculated by multiplying its length by its width. The length is given as 5, but since there is an extended rectangle on the bottom left, we need to subtract the length of the smaller rectangle (2) from it. So the length of the larger rectangle is 5 - 2 = 3. The width is given as 4.
Therefore, the area of the larger rectangle is 3 * 4 = 12 square units.
The area of the smaller rectangle is simply the product of its length and width, which are given as 2 and 3 respectively. Thus, the area of the smaller rectangle is 2 * 3 = 6 square units.
To find the total area of the composite figure, we add the areas of the larger and smaller rectangles together: 12 + 6 = 18 square units.
Therefore, the area of the composite figure is 18 square units.
