Answer:

Door 3 diagonal 3√10 feet

Step-by-step explanation:

The diagonal of a rectangle is the hypotenuse of a right triangle whose legs are the side lengths of the rectangle. That is, the diagonal of a 9 ft by 3 ft rectangle will have length ...

d = √(9² +3²) = √90 = 3√10

Any "9 ft by 3 ft" figure that has a diagonal different from this is not a rectangle. To fit the rectangular opening, we want a rectangular door—one with a diagonal of 3√10 feet.

For this, we will be using dimensional analysis as such:

$\frac{24900\ mi}{1}*\frac{5280\ ft}{1\ mi}*\frac{12\ in}{1\ ft}*\frac{2.54\ cm}{1\ in}*\frac{1\ m}{100\ cm}=\frac{4007266560}{100}=40072665.6\ m$
