The Puerta de Europa towers are two towers leaning against each other, built on an avenue in Madrid, Spain. The inclination of the towers is $15^{\circ}$ with the vertical and they each have a height of 114 m (the height is indicated in the figure as segment AB). These towers are a good example of an oblique prism with a square base and one of them can be seen in the image.
Using 0.26 as the approximate value for the tangent of $15^{\circ}$ and two decimal places in operations, one discovers that the base area of this building occupies on the avenue a space
(A) less than $100 \mathrm{~m}^{2}$. (B) between $100 \mathrm{~m}^{2}$ and $300 \mathrm{~m}^{2}$. (C) between $300 \mathrm{~m}^{2}$ and $500 \mathrm{~m}^{2}$. (D) between $500 \mathrm{~m}^{2}$ and $700 \mathrm{~m}^{2}$. (E) greater than $700 \mathrm{~m}^{2}$.
