A cubby house is built in a tree on two levels, the lower level being 10m above the ground, while the upper level is another 5m vertically higher.

the ladder from the ground to the lower level is 12m long. Sam wants to construct another ladder to go from the ground 1m further from the base of the tree to the top level. how long should he make this ladder?
