Question

the area of the four walls of a room is 156 m square the breadth and height of the room are 8m and 6M respectively find the length of the room

Answer 1

✔✔heya here is ur answer!!!

_____________________________

given , area = 156m
breadth = 8m
height = 6m
length = ?

area = 2h (l+b)

=> 156 = 2× 6 (l+8)

=> 156 = 12 ( l+8)

=> 156/12 = (l+8)

=> 13 = l+8

=> 13-8 = l

=> l = 5

therefore length = 5cm


THANK YOU ✌✌

HOPE IT HELPS YOU ☺☺

Answer 2

Area of the four walls of a room = 156m^2

given Breadth= b = 8 m

height= h = 6m

area of a four walls room=

2h(l + b) = 156

2*6(l + 8) = 156

12(l + 8) = 156

l + 8 = 156/12

l + 8 = 13

l = 13 - 8 = 5

there for length= 5m
