The height of building is 35 feet

Solution:

Given that,

Sam is 6 feet tall and his shadow is 3.6 feet tall

The shadow of building is 21 feet long

To find: height of building

We can solve this by setting up a ratio comparing the height of the building to the height of the Sam and shadow of the building to the shadow of the Sam

Let us consider,

= height of building

= height of Sam

= shadow of building

= shadow of Sam

Therefore,

Substitute the values,

Thus height of building is 35 feet
