Question

Jack is standing next to a monument in the city square. His shadow is 18 feet long. The shadow of the monument is 150 feet long. If Jack is 6 feet tall, how tall is the monument?

25 feet

50 feet

75 feet

450 feet

Answer 1

make a proportion:
\[\frac{6}{18} = \frac{x}{150}\]
now solve for x. You should get x = 50 feet

Answer 2

Jack is 6 feet
his shadow is 18
His shadow is 3x longer than him
So since the monument is 150 feet long

all you have to do is multiply 150 x 3= 450 feet tall

Answer 3

@aussy123 It says the building's shadow is 150 ft long, not the building is 150 ft tall

Answer 4

yea thanks I forgot to put the shadow of the monument...thx for pointing that out
