Question

He who is 2 m tall has a shadow of 150 cm. If the length of the shadow of a building is 24 m, what is the height of the building?

Answer 1

height of man = 2m
shadow = 150cm = 1.5 M

height of building = x
shadow = 24m

so,
2/1.5 = 24/ x
x = 18 m

Answer 2

// is known //

height him = 2m

his shadow = 150cm

shadow of the building = 24m

height of building = x

// comparison worth //

height him / her shadow = height of building / shadow of the building

// find the height of the building //

height him / her shadow = height of building / shadow of the building

2m / 150cm = x / 24m

x = 2m / (150 (1 / 100m)) × 24m

x = 2m / 1.5m × 24m

x = 48m / 1.5

x = 32m

So the height of the building is 32 m
