copyright©amberpasillas2010 Area of Irregular Figures Find the area. A method of estimating the area of an irregular figure is to count the number of squares the figure covers. Count the full squares: Count the half-full squares: Calculate how many half squares put together make full squares The area of the figure is 15 square units = 15

copyright©amberpasillas2010 Area of Irregular Figures Find the area. A method of estimating the area of an irregular figure is to count the number of squares the figure covers. Count the full and almost-full squares: Count the half-full squares: Calculate how many half squares put together make full squares. The area of the figure is about 14 square units = 14
