The graphical method to find area of an irregular shaped plane figure
Answers
Answer:
Explanation:
To find the area of an irregular shape, there coud be two ways.
One, if shape is a polygon made using all straight lines. Just join the two farthest points (we will call this line the diagonal) and now draw perpendiculars from other points on to this diagonal. The figure is then divided into tiangles and trapeziums. and we can find its area.
Two, if the shape is not made using straight lines. Then we impose graph on it. Now we can find its area by counting the squares falling in the region covered by the shape. First we count squares completely covered and then we approximate area of partially covered squares, by counting say more than half covered, less than half covered. When everything is added, we get approximate area of the irregular shape.
