Hey mate!

Here is your answer > >

Total Surface area of cuboidal room=800 m^2

2 (lb+bh+hl)=800

lb+bh+hl=400........... (1)

Now, Curved surface area of cuboidal room=2 (l+b)*h=300 m^2

lh+bh=150......... (2)

Substituting the value of (2) in (1)

lb+150=400

lb=400-150

lb=250 m^2

Area of the base= lb=250 m^2

Hope it helps!
