Answer 1

Step-by-step explanation:

Hi ,

dimensions of the room is

length ( l ) = 12 m

breadth ( b ) = 7 m

let the height = h m

area of four walls the room = 266 sq m

[ ( l + b ) h ] /2 = 266

[ ( 12 + 7 ) h ] = 266 × 2

19h = 266 × 2

h = ( 266 × 2 ) / 19

h = 14 × 2

h = 28 m

I hope this helps you.
