Answer 1

Hii friend.. Nice question..

Here is ur answer :

Length of class room = 10 m

Breadth of class room = 8 m

Height of class room = 5 m

Area of 4 walls = 2 ( length + breadth ) × height

= 2 ( l + b) h

= 2 ( 10 + 8 ) 5

= 2 × 18 × 5

= 2 × 90

= 180

Answer is 180 m.

HOPE IT HELPS YOU..
