Anewly-planted tree needs to be staked with three wires. each wire is attached to the trunk 3 ft. above the ground, and then anchored to the ground 4 ft. from the base of the tree. how much wire is needed for 6 trees?

Each treee has 3 wirds
so 3 feet from the ground
4 feet from the tree
use pythatorean theorem to find staright measure from tree to ground
a^2+b^2=c^2
3^2+4^2=c^2
9+16=c^2
25=c^2
square root both sides
5=c

the legnth is 5

3 wires per tree
3 times 5=15

6 trees
15 times 6=90

90 feet of wire is needed
