Detailed Solution

The total length of the ribbon lies in the range is

1.25 m - 1.35 m

.
Here, we can say that the ribbon is folded

5

times. So, from the figure, the length of the ribbon is given by

\Rightarrow (27.5 - 2) \times 5

\Rightarrow 25.5 \times 5

= 127.5 cm

Now, we will convert

127.5 cm

into a

meter

127.5 cm = 1.27 m

So, the range in which

1.27 m

lies is

1.25 m - 1.35 m
