Answer 1

Answer:

1m 65cm

Step-by-step explanation:

12 trouser = 1980cm

1 trouser = 1980/12=165 cm = 1m65cm

Answer 2

Answer:

There is 185 cm cloth is needed for each such trouser.

Since we have given that

Number of trousers of the same size = 8

Length of total cloth is needed = 14 m 80 cm

Since we know that

1 m = 100 cm

14 m = 1400 cm

14 m 80 cm = 1400 cm +80 cm = 1480 cm

So, Length of cloth for each such trouser is given by

\begin{gathered}\dfrac{\text{Length of cloth}}{\text{Number of trousers}}\\\\\\=\dfrac{1480}{8}\\\\=185\ cm\end{gathered}

Number of trousers

Length of cloth

=

8

1480

=185 cm

Hence, there is 185 cm cloth is needed for each such trouser.
