EXPLANATION
Using a composite figure to approximate the area of the figure will give us the needed surface,
The area of the composite is approximately the area of the squares:
Area of square:
A= base * height = 1.0*1.0 = 1 cm^2
Since we have approximately 22 squares inside the figure, the approximate area will be as follows:
[tex]Area_{composite\text{ figure}}=22*1cm^2=22cm^2[/tex]
Therefore, the solution is approximately 22 square units.
