For the final action project in Street Math, we looked at how math is used to create certain types of atmosphere in urban planning. I was interested in how architects maximize or minimize space without creating atmospheres of claustrophobia or exaggerated distance. To do this, it is important to calculate area of a room. Below is an example problem using area and an explanation of how it relates to urban planning.
An image that represents how architects can use area to affect the atmosphere of a space is this photo of a tiny room:

The use of area is effective in minimizing space, and to some it may create a comforting atmosphere, but to others it may make them feel claustrophobic.
