Height of the building = 12meter

distance of bottom of ladder from the building = 5meter

Unknown

Length of the ladder = ?

Solution:

To solve this problem, we use the pythagoras theorem

Hypotenuse = $\sqrt{opposite ^{2} + adjacent^{2} }$

Hypotenuse = ?

Adjacent = 5m

opposite = 12m

Hypotenuse = $\sqrt{12 ^{2} + 5^{2} }$ = $\sqrt{169}$ = 13m
