First let's get the area of the first small rectangle to find the area of a rectangle you multiple length and width so 3 m x 2 m= 6 m
Rectangle two same formula
Length times width = 3 m times 3 m which is 9
And the last rectangle 9 m times 3 m is equal to 27 m
Now to find the area of the whole shape you add all of the above
So 9+27+6= 42 m
So the final answer is 42 m which is the area of the figure
