Question

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

Answer 1

Answer: 226.2 m

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.
