Area is the number of square units needed to cover a flat surface.Some Metric Units for measuring area are square centimeter,

square decimeter, or square meter.

Find the area of the a figure by counting the shaded squares.

1 square unit

= 6 square cm

Sometimes you need to count half squares to find the area of a figure.1 whole square + 2 half squares

2 half squares = 1 whole square1 + 1 = 2 square units

Sometimes you need to estimate the area of a figure.4 whole squares + 4 almost whole squares + 4 about half squares

4 half squares = 2 whole squares4 + 4 + 2 = about 10 square units
