To solve the problem of finding the area by counting squares, we need to count the number of shaded squares in each figure. Each shaded square represents 1 square unit. Let's go through each figure step by step.
Figure 1:
- Count the shaded squares: There are 7 shaded squares.
-
Area = 7 square units
Figure 2:
- Count the shaded squares: There are 10 shaded squares.
-
Area = 10 square units
Figure 3:
- Count the shaded squares: There are 8 shaded squares.
-
Area = 8 square units
Figure 4:
- Count the shaded squares: There are 9 shaded squares.
-
Area = 9 square units
Figure 5:
- Count the shaded squares: There are 6 shaded squares.
-
Area = 6 square units
Figure 6:
- Count the shaded squares: There are 9 shaded squares.
-
Area = 9 square units
Figure 7:
- Count the shaded squares: There are 6 shaded squares.
-
Area = 6 square units
Figure 8:
- Count the shaded squares: There are 7 shaded squares.
-
Area = 7 square units
Figure 9:
- Count the shaded squares: There are 6 shaded squares.
-
Area = 6 square units
Figure 10:
- Count the shaded squares: There are 12 shaded squares.
-
Area = 12 square units
Figure 11:
- Count the shaded squares: There are 12 shaded squares.
-
Area = 12 square units
Figure 12:
- Count the shaded squares: There are 9 shaded squares.
-
Area = 9 square units
Figure 13:
- Count the shaded squares: There are 6 shaded squares.
-
Area = 6 square units
Figure 14:
- Count the shaded squares: There are 8 shaded squares.
-
Area = 8 square units
Figure 15:
- Count the shaded squares: There are 5 shaded squares.
-
Area = 5 square units
