Question

Santa wants to be able to use his ladder on either side of this chimney. Determine the length

of the ladder he would need so that it would work on both sides.

Answer 1

6.71 ft

Explanation:

sqrt(3² + 6²) = sqrt(45)

sqrt(45 - 2²) = sqrt(41) > 6

Length should be sqrt(45),

Or 3sqrt(5) or 6.71 ft (3sf)
