Answer 2

HEY buddy.....!!! here is ur answer

Given that the breadth of the room. = 10m.

and the height of the room = 4m.

let the length of the room = x meter

According to the question.....

=> 2h(l+b) = 168m.²

=> 2 × 4 (10+x) = 168

=> 8(10+x) = 168

=> 10+x = 21

=> x = 21–10

=> x = 11m.

So, the length of the room will be 11 meter.

I hope it will be helpful for you....!!

THANK YOU ✌️✌️
