    Distance d = AD (the hypotenuse)

    d^2 = 127^2 + 64^2

    d = √(20225)

    ==> 5√(809) yds

    ≈142.21 yards

    ...................A (starting point)

    ................../.|

    ................/...|

    ............../.....| 104 - 40 = 64 yds

    .........D./____|

    ...........|..127.|

    ...........|---------| 104 yds

    .........C..........B

  • if you draw it out it becomes quite simple you go south 104 then west 127 then back up north 40. Draw a line from the start to the finish then a line from the finish towards the first line going south. you will see a triangle. one side is 127 the other side will be 64 since you traveled back up 40. now you just you the p - theorem to find your answer a^2 + b^2 = c^2

    140 yards (50 yards long by 20 yards wide times 2)
