Question

Suppose a 1.2 m antenna is installed on top of a building that is 225 m tall,

What is the new total height of the building, including the antenna, expressed
with the correct number of significant figures?

Answer 1

Answer: 226.2 m

Step-by-step explanation:

If we want to find the new total height
`H` of the building, we have to add to its initial height
`h_(B)=225m` the height of the antenna
`h_(A)=1.2m`, as follows:

`H=h_(B)+h_(A)`

`H=225m+1.2m`

Then:

`H=226.2m` This is the new total height of the building.
