Given the Letter E, you can divide it into these figures:
Notice that you can divide it into 3 equal rectangles and 1 large rectangle.
• The area of a rectangle can be calculated using this formula:

Where "l" is the length and "w" is the width of the rectangle.
In this case, you can identify that:

Therefore, the total area of the equal rectangles is:

Since:

You get that the area of rectangle 1 is:

Therefore, the total area of letter E is:

• In order to find the perimeter of the letter E, you need to identify the length of each side. See the picture below:
Therefore, adding the lengths, you get that the perimeter is:


Hence, the answer is:
