Answer 2

The height of room is 3.57 m

Step-by-step explanation:

Length of room = 4.2 m

Breadth of room = 3 m

Area of 4 walls = 2(l+b)h

Area of 4 walls = 2(4.2+3)h

The area of four walls of a room is 51.2 m square

So, $2(4.2+3)h = 51.2$

$h=\frac{51.2}{2(4.2+3)}$

h=3.57 m

Hence The height of room is 3.57 m
