Solution

The correct option is C $2 (l + b) h$
The length of the room $= l$
The breadth of the room $= b$
The height of the room $= h$

Therefore, the area of four walls will be
$= 2 \times (l h + b h)$
$= 2 (l + b) h$

Hence, this is the answer.

If l, b, h are the length, breadth and height of a room, then area of 4 walls will be

The correct option is C 2(l+b)hThe length of the room =lThe breadth of the room =bThe height of the room =hTherefore, the area of four walls will be=2×(lh+bh)=2(l+b)hHence, this is the answer.
