Answer 2

Answer:

$let \: dimensions \: of \: rooms \: are$

$length = 1 \: m$

$breadth = 10 \: m$

$height = 4 \: m$

$given.$

$area \: of \: four \: walls \: of \: the \: room = 168 \: m$

$2(l + b)h = 168 \: m$

$2(l + 10) 4 = 168$

$l + 10 = 168(2 \times 4)$

$l + 10 = 21$

$l = 21 - 10$

$l = 11 \: m$

$therefore.$

$answer \: is \: 11$
