To solve this problem you must apply the proccedure shown below:
1. You have the following standard form for the hyperbola given in the problem above: (x-2)^2/36 - (y+1)^2/64=1
2. Therefore, you can calculate the lengtn of the transverse axis as following:
Length of transverse axis=2a
a^2=36
a=√36
a=6
Length of transverse axis=2(6)=12
Then, the answer is:12
