The area of this is 46 meters square because the area of the rectangle is 40 meters square, and the area of the triangle is 6 meters square, so i just add all of it together to get 46 meters square. Hoped it help! Finally, the area of the triangle is 1/2 times base times height, so we already have base is 4m and height is 3m. As a result, 1/2 times 4 time 3 equal 6 meters square. Hoped it help!
