we can do length times width times 1/2 ok, so look, we got some triangles 4 of them they are 12.6/2 by 10.4/2, or 6.3 by 5.2 area of triangle=1/2bh so 1/2 times 6.3 times 5.2=16.38 4 of them so times 4 4 times 16.38=65.52 squaer feet 3rd option
Basicaly we will start out with dividing 10.4 divided by 2 to get 5.2 then divide 12.6 divided by 2 to get 6.3. 12 is the line in the middle of the 4 triangles. 5.2 is the line down the middle of the 4 triangles but what you would do is ust have 5.2 on 1 half which is 2 triangles and then the lower 2 triangles line. From there you multiply 5.2 times 6.3. I dont know really how to explain it. But the answer is C 65.52
