Answer: No, we cannot find for its length as we can see that variables got cancelled so, we are not able to find any value for 'y'.
Step-by-step explanation:
Since we have given that
Let length of room's floor be y
Let width of a room's floor be y-5
Perimeter of room's floor be 4y+1
As we know the formula for " Perimeter of rectangle ":
[tex]Perimeter=2(Length+Width)\\\\Perimeter=2(y+y-5)\\\\4y-1=2(2y-5)\\\\4y-1=4y-20\\\\4y-4y=-20+1\\\\0\neq -19[/tex]
No, we cannot find for its length as we can see that variables got cancelled so, we are not able to find any value for 'y'.
