Question

String A is 35 cm long. String B is five times as long as String A. Both are necessary to create a decorative bottle. Find the total length of string needed for 17 identical decorative bottles. Express your answer in meters

Answer 1

Length of string A = 35 cm

Length of string B = 5 times as long as String A

= $5\times35$ = 175 cm

Assuming that whole length of string A and B is used to decorate one bottle

So if ,35 cm of string A and 175 cm of string B is needed for 1 bottle.

Hence, for 17 bottles string A needed is = $35\times17=595$ cm

For 17 bottles string B needed is = $17\times175=2975$ cm

In meters the length becomes;

1 cm = 0.01 meter

String A = 595 cm = 5.95 meter

String B = 2975 cm = 29.75 meter

And if these are added they become = 5.95+29.75 =35.70 meter

So, total length needed is = 35.70 meter ( if string A and B are added together)

Otherwise total String A needed is 5.95 meters and string B needed is 29.75 meters.
