About 12.56 units. 
Solve for x by plugging in values into Pythagorean theorem.
a^{2} +b^{2} = c^{2}
x^{2} +(x+12)^{2} = 34^{2}
Simplify
2x^{2} + 24x+144 = 1156
Subtract 144 from both sides
2x^{2} + 24x = 1012
divide both sides by 2
x^{2} + 12x = 506
complete the square
x^{2} + 12x + 36 = 506 +36 . = (x+6)^2 = 542
take the square root of both sides.
x+6 = 23.28
subtract by 6 to get  about 17.28 for x.
Plug in values for x to get distance traveled on outside of the yard.
17.28 + (17.28 +12) = 46.56
subtract 34 from the length to get the difference in travel. 46.56-34=12.56

*not drown to scale
bulgar [2K]

Answer:

26.9 inches

Step-by-step explanation:

2x Pythagorean theorem

First we find the length of AC with ABC. AC is the hypotenuse of triangle ABC.

AC = sqrt(7^2+24^2) = sqrt625 = 25.

Now, AD is the hypotenuse of ACD. So AD = sqrt(25^2+10^2) = sqrt(725) = 26.925824 which is about 26.9 inches.
