Answer to Problem 19E
The area of the polygon is
Explanation of Solution
Formula used:
Area of a polygon on square sheet is the number of full squares, half squares and almost-full squares that covers the surface of the figure.
Almost-full squares are counted as full squares.
Two half squares are equal to one whole square.
The squares which are less than half full are not counted.
Calculation:
Recall that area of a polygon on square sheet is the number of full squares, half squares and almost-full squares that covers the surface of the figure.
To evaluate the area of the polygon, we need to count the number of full squares, half squares and almost-full squares.
Number of full squares
Number of almost full squares
Recall almost-full squares are counted as full squares.
Number of half squares
And we know that two half squares are counted as one whole square.
So,
There are 6 squares which are less than half full, so, they won’t be counted.
To estimate the area of the polygon, add the above number of squares.
Thus, the area of the polygon is
