On the brick "Women's Walkway" from the intersection of 33rd and Chestnut to the intersection of 34th and Walnut in Philadelphia, I became fascinated with the pattern of the bricks.
Here is an area that I'm filling with the pattern:
I thought it was economical how some bricks were cut in half and some of the halves were also cut in half to neatly fit to the edges.
If the top faces of the uncut bricks are 2 units by 1 unit,
how many bricks would it take to cover the full area of the pattern shown above?
what is the area?
