Well, knowing that 2 right triangles placed together would make up a rectangle, to find area of the right triangle, all what you need to do, is find the area of the rectangle and divide it by 2. This should be the area of one of the right triangles, add up the same value twice and you should get the area of the original rectangle which would be the product of 17 inches and 30.6 inches. Make sure to convert the final result into m^2. So from in^2 to cm^2 and then to m^2.
