"a person 2 m tall casts a shadow 5 m long. at the same time,a building casts a shadow 24 m long. how tall is the building?"

Set up a proportion:
2m (tall) / 5m (shadow) = x (tall) / 24m (shadow)
5x = 2(24) {cross-multiplied}
5x = 48 {multiplied 2 by 24
x = 48/5 {divided both sides by 5}
x = 9.6 m tall {the building}
