The wire , the distance away from the
trunk and the trunk will form a right
angled triangle
The wire = hypotenuse
The trunk = height
The distance on the ground
to the peg from the trunk
= base
By Pythagoras theorem
(Trunk height)^2 +
Ground distance)^2
= (length of wire)^2
(3)^2 + (4)^2 = (length of wire)^2
9 + 16 = (length of wire)^2
length of wire = square root of 25
Length of wire = 5ft
6 trees will require 6 x 5ft = 30 ft.
Hope this helps :-)

For each Tree we need equal number of three wires from Tree trunk to the ground.
A simple Trigonometry will solve the question, thus;
Using Pythagoras, (Sum of the squares of the Adjacent and Opposite equals the square of the Hypotenuse)
Hyp%5E2+=+Adj%5E2+%2B+Opp%5E2
Hyp%5E2+=+4%5E2+%2B+3%5E2
Hyp%5E2+=+16+%2B+9+
Hyp+=+sqrt%2825%29
Hyp+=+5+
So for one rope, you will need 5Ft. Therefore you will be needing 5 X 3 for each Tree. => 15.
The entire pack of six Trees will be 15x6 => 90.
Final Answer = 90 Ft.
