Area of building is
.
<u>Step-by-step explanation:</u>
Here we have , a figure in given below picture where we have to find volume of this office building , Let's find out:
If we look closely we see that it's basically cuboid with dimensions 50 m by 110 m by 70 m . But there's one small cuboid sliced off from this cuboid with dimensions 50 m by 10 m by (110-90) m i.e. 50 m by 10 m by 20 m .
Area of building = Area of larger cuboid - Area of smaller cuboid
Area of cuboid = 
⇒ Area of building = Area of larger cuboid - Area of smaller cuboid
⇒ 
⇒ 
⇒ 
Therefore, Area of building is
.
