Remember that the area of a square is just one of its sides squared. 
where
is the area of the square
is one of the sides of the square
Unit square is a square whose sides have length 1, so lets use our formula to find the volume of one unit square:
We now know that each one of the squares has area 1 unit squared. Since there are 28 unit square in our figure, we are going to multiply the area of a unit square by 28 to find the area of our figure:
Area of the figure=
units squared
We can conclude that the area of the figure is 28 units squared.
