answer: 11378.583 feet (approx)
let from the foot of the line that shows the distance of the plane from the road the distance of first car is x feet and the distance of second car is y feet,
thus, by the below figure,
we can write,
similarly, by the below diagram,
thus, the total distance between the car = x + y = 4023.62097651 + 7354.96223472= 11378.5832112≈11378.583 feet
length of other diagonal is 17 feet.
we have given,
length of rectangular window = 15 feet
width of rectangular window = 8 feet
diagonal length = 17 feet
we can also apply pythagoras theorem to check if it is a diagonal of rectangle or not
i.e 17² = 15² + 8²
or 289 = 225 + 64
or 289 = 289
hence given diagonal length is the diagonal length of rectangular window.
diagonals joining opposite vertex of rectangle are equal.
.since the length of one diagonal is 17 feet.
therefore length of other diagonal will be 17 feet as well.
