Answer 1

Hello Mate!

So length of classroom = 11 m

Breadth = 8 m

Height = 5.5 m

So, area of 4 walls + area of floor

= 2( l + b )h + lb

= 2( 11 + 8 )m × 5.5m + 11m × 8m

= 11 × 19 m² + 88 m²

=> 297 m²

Hence answer is 297 m²

Have great future ahead!

Answer 2

Heyyyy mate

here is your answer

given , length of room = 11m

and breadth of room= 8 m

and high = 5.5 m

according to question,
area of four walls= 2(l+B)×h

and also add the area of floor= l×b

so 2(11+8)×5.5+11×8

>>> 209+88=297m^²

hope it help you
