Answer 1

I can't and why?

Answer 2

if you count the number of shaded squares, where each square has area of 1 cm^2 , that will be your area

Answer 3

just count the squares :D

Answer 4

The length of each side of each square is 1cm. The area of a square is:\[Area=(length)^2\]So the area of each square is:
\[1cm^2\]
Each square contributes \[1cm^2\]of area. Therefore the total area of the shaded region is the number of shaded squares.
