To find the area of the composite figure, we need to break it down into smaller, simpler shapes and then add their individual areas together.
In this case, we can see that the composite figure is made up of a rectangle and two half circles.
First, we need to find the area of the rectangle. The length of the rectangle is 8 units and the width is 4 units. The formula for finding the area of a rectangle is length x width, so the area of the rectangle is 8 x 4 = 32 square units.
Next, we need to find the area of the two half circles. To find the area of a circle, we use the formula A = πr^2. However, since we are dealing with half circles, we need to divide the area by 2.
The radius of the half circles is 2 units (half of the width of the rectangle). Plugging this into the formula, we get:
A = (Ï€ x 2^2)/2 = (Ï€ x 4)/2 = 2Ï€ square units
Now, we add the area of the rectangle and the area of the two half circles together:
32 + 2π ≈ 38.28 square units
So, the area of the composite figure is approximately 38.28 square units.
