To solve this problem, we can use the concept of similar triangles. The height of the building is proportional to the length of its shadow.
Let x be the height of the building.
Using the given information, we can set up the following proportion:
(x/30) = (4/3)
To find x, we can cross multiply:
3x = 120
Dividing both sides of the equation by 3, we get:
x = 40
Therefore, the height of the building is 40 feet tall.
A building casts a shadow 30 feet long. Meanwhile, a kid 4 feet tall casts a shadow 3 feet tall. How tall is the building?
40 feet tall
4 feet tall
50 feet tall
