Answer: 226.2 m

Explanation:

If we want to find the new total height [tex]H[/tex] of the building, we have to add to its initial height [tex]h_{B}=225m[/tex] the height of the antenna [tex]h_{A}=1.2m[/tex], as follows:

[tex]H=h_{B}+h_{A}[/tex]

[tex]H=225m+1.2m[/tex]

Then:

[tex]H=226.2m[/tex] This is the new total height of the building.
