To calculate the area of the letter we in the picture, we can divide it in rectangles.
There are different ways of doing it. Let's divide like this:
So, we have 4 rectangles.
The left one has a height of 3.45m and the length is not given directly, but we know that is the difference between the total length minus the length of the top rectangle:

So, the first rectangle is 3.45m x 0.9m, so the area 1 is:

The top rectangle is 200cm (2.00m) by 75cm (0.75m). So, the area 2 is:

The middle triangle is 1.2m by 75cm (0.75m), so the area 3 is:

And the bottom rectangle is the same as the top one, so the area 4 is equal to the area 2:

The total area is the sum of the areas 1 to 4:

Thus, the area of this letter E is 7.005 m².
