Area

In class, we learned how to find the area of an parallelogram, and how to find the area of a figure that is not on a peice of grid paper. First, to make it easier, you can count up all of the full squares in the figure. Then, count up all of the half squres, and then add the two halfs together to make one whole one. If you want to also find the area of a figure, you can find it adding up length+ width,+ length+ width. When you want to find the area of a figure, add up the vertical side of the shape up first, and then the horizontal side of the figure. Then, times them together, and then you should get the area of the figure. What makes the shape easier for me to follow, and get the area if, and we also did it in class. We had a triangle that would be part of the shape, and then move it over to the oppisite side of the figure, to get a triangle ( square) Then, you find the area of the shape easier that way instead of having a weird looking shape to find the perimeter and area of it.
