Question

A ladder leans against the side of a house the top ladder is 16 ft from the ground the bottom of the ladder is 12 ft from the side of the house find the length of the ladder if necessary round your answer to the nearest tenth

Answer 1

`{h =}^(2) = {p}^(2) \: + {b}^(2)`

`{h}^(2) = {16}^(2) + {12}^(2)`

`{h}^(2) = 256 + 144`

`h = √(400)`

`h = 20`

therefore the length of the ladder is 20ft
