-
- Given:-
one strip width = x
two strips width = y
So, after first strip, the width of each strip is (y-x)
Here given z strips, Therefore
final width = (z-1)*(y-x)+x

- zx
for 1 is x for z will be zx - 12 years agoHelpfull: Yes(12) No(6)
- since strips are placed one over other....so nothing will change..

- width will not change but length will increase
width after placing z strips one over the other = x
length after placing z strips one over the other =y.z/2 - 12 years agoHelpfull: Yes(1) No(2)
