String a is 35 centimeters long. string b is 5 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.

First you convert centimeters to meters which will be 35 centimeters-> 0.35 meters

Once you have that, you multiply String A's length (0.35 m) by 5 to find String B's length which will be 1.75 meters.

Now that you have the two lengths you multiply each by 17.
 
17 x 1.75 = 29.75 and 17 x 0.35 = 5.95

Now you just add 29.75 and 5.95 and you get your answer which is
 
35.7 meters
