We will learn how to find the area using square paper.
Let us take a squared paper and draw any shape. We can find the area covered by that shape by counting the squares.
Rules to find area are as follows:
(i) Count the number of full squares.
(ii) Count the number of half squares (2 triangles make 1 square)
(iii) If the square is more than half count it as 1.
(iv) If the square is less than half, exclude, that is , don’t count.
(v)Thus, we can get an approximate area of the figure.
Example
Number of full squares = 3
Number of half squares = 4 i.e., 2 squares
Number of squares less than half = 2 (excluded)
Therefore, total area of the figure is 3 squares + 2 squares = 5 square units.
