Area of building is .

Step-by-step explanation:

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 .
