let the dimensions of the room are
Length =l m
breadth =b m
Height = h=4m
perimeter = 2(l+b)
area of the four walls = 80m^2
2(l+b)*h=80
2(l+b)= 80/h
therefore
perimeter = 80/4
=20m
Length =l m
breadth =b m
Height = h=4m
perimeter = 2(l+b)
area of the four walls = 80m^2
2(l+b)*h=80
2(l+b)= 80/h
therefore
perimeter = 80/4
=20m
