Start by finding the area of the middle rectangular section. Multiply 6.3 and 8 for a product of 50.4. Next, find the area of one of the side triangle sections. To do so, multiply 5 and 6.3 and then divide by 2, which results in 15.75. Because the triangular sections are identical, you can simply multiply 15.75 by 2, which gives you 31.5. Finally, add 31.5 and 50.4, for a total area of 81.9 inches squared.
Answer: 81.9 in^2
