A pole that is 2.9m tall casts a shadow that is 1.39m long. At the same time, a nearby building casts a shadow that is 36.75m long. How tall is the building.

2.9 / 1.39 = x / 36.75
Cross multiply:
1.39x = 2.9 * 36.75
1.39x = 106.575
x = 76.673 m

A 12 ft. building casts a shadow 4 ft long if a statue casts a shadow 3 ft long, then how tall is the statue?
