How many feet long is the shadow of a 15-foot flagpole if a 5-foot woman standing at the base of the flagpole has a shadow that is six feet long?
If a 5 foot woman casts a 6 foot shadow then you can calculate how much longer a shadow is than the object as 6/5=1.2
Then you can find the shadow by multiplying 15 by 1.2
Lenght=18 feet
