The area of the given composite figure is 34 square feet
<h3>Area of rectangle</h3>
Area of the rectangle = length * width
<h3>Get the area of the given composite figure</h3>
For the composite figure shown:

Area = 24 + 10
Area = 34 square feet
Hence the area of the given composite figure is 34 square feet
