# Find the Area of four walls of a room 13 m long and 8 m wide and 5 m high

- 200 cm²
- 250 m²
- 210 m²
- 230 m²

## The correct answer is: 210 m²

### To find the area of four walls of a room.

It is given that length, breadth and height of a room are 13 m, 8 m and 5 m respectively.

Area of four walls of the room is: $2h(l+b) = 2 x 5(13 + 8) = 210 m²$

Therefore, the area of four walls of a room is 210 m².
