Question 168951
Where appropriate, round to three places. 
A car dealer advertised a big sale by stretching a string of banners from the top of the building to the edge of the driveway. If the building is 16m high and the driveway is 31m from the building, how long is the string of banners?
-----------------------
It's {{{sqrt(31^2 + 16^2)}}}
= sqrt(961 + 256)
= sqrt(1217)
= 34.886 meters.
