Question

the area of four walls of a room is 168 m² the breadth and height of the room are 8 m and 6 m respectively . The length of the room is ​

Answer 1

Answer:

Step-by-step explanation:

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

168 $m^{2}$ = 2 ( l + 8m) 6m

$\frac{168m^{2} }{6m}$ = 2l + 16m

28m = 2l + 16m

28m - 16m = 2l

12m/2 = l

6m = l

Therefore, the length of the room is 6m.
