A building across the street casts a shadow that is 2424 feet long. Your friend is 66 feet tall and casts a shadow that is 44 fe
salantis [7]
If 66 feet is a typo for 6 feet, then the answer is 330 feet long. Multiply 6•7.34= 44.04 round to 44. 2424/7.34= 330.245 round to 330. This is the height of the building.

If there is no typo 66/3= 22•2= 44

2424/3= 808•2= 1,616 feet tall.
