Now just add all the areas we found both triangles and the rectangle.

Yes 32 but you want to get int he habbit of  writng it's unit on the side so 32m²

Okay so now we know that area of the triangle ocoupies 2 meters of the top of the parallogram which leaves us with 4 left and we knwo the height of it is 8 fromt he side of the triangle so using thins information can you find the area' of the rectangle?

Are you ready to do the rectangle?

That is the explanitory way so you want to multiply 1/2 to 2 and 8 well you set them up liek this 

\(\frac{1}{2}*\frac{2}{1}*\frac{8}{1}\) See where I'm goign here if you ahve a whole number that needs to be multiplied by a fraction then you put that number on the top as the numerator then you put just a 1 as the denominator.

Does that make sense?

When you multiply whole numbers with a fraction you put 1 as the denominator multiplly all the numerators and then multiply all the denominators. your final roduct will lead you to division.

Well the formula for the triangle is \(\frac{1}{2}* Base * height = Area\)

and you want to get in the habbit of using that instead of just dividing at the end I woudl use that trick once your abosoulty comfortable with the actual way to solve for the area of a traingle  

so it would be \(\frac{1}{2}*\frac{2}{1}*\frac{8}{1} =\frac{16}{2}\) 

and 16 over 2 indicates dividion so tyou divide 16 by 2 which results in 8m²

Okay so you got the first part right of first triangle but the second part we still have another triangle and rectangle's area's to find 

Now we can palce the triangle in the other corner jsut like the first one but it facing down this time, it's base and heigth will be the same as the one as before so what will the area of the second triangle be?

Yes beause in this problem your assuming that you can't fit anymore in the bag so it's ideal to round it to the next number because you will need another bag. Generaly it we would round it to 1.4 or maybe just 1 but since you have only whole numbers to choose from you round it to the next whole number.
