<h2>A = 96ft^2</h2><h2 />
A simple method of calculating Area is multiplying the Length times the Width. It is much harder to calculate the entire thing all at once, so it is easier to rather keep the shapes separate.
10 x 8 = 80. This is the area of your first shape, the Rectangle.
You can do the same with the triangle, although triangles are only half a square. You also only multiply the flat sides, not the slanted side, the side with 8.9.
8 x 4 = 32. Because the shape is a triangle wedge, half a square, you divide your answer, 32, by 2, to get half of 32, which is 16.
Then add the two areas, 16 and 80, which is 96.
(The little box in the bottom right corner of the square is just an angle, it represents that it is a right angle, ignore it if you didn't know what it was.)
