Question

The roof of a building is in the shape of the hyperbola y2 - x2 = 38, where x and
y are in meters. Determine the distance, w, between the outside walls.
A = 7 m

Answer 1

What is A? area?!

Answer 2

I'm not sure what the "A" represents. If A = x, the y-coordinates are ± 9.3273791... I guess the distance w is approximately 18.6547... m

Answer 3

There is a small a associated with hyperbola\[x ^{2}/a ^{2} - y ^{2}/b ^{2}=1\]
