Question

String A is 35 centimeters long.string B is 5 times as long as string a .both are necessary o create a decorative bottle. Find the total length of string needed for 17 identical decirative bottes .express your answer in meters.

Answer 1

String A is 35 cm long, string B is 5 times as long as string A, then string B is 35·5=175 cm long. In total both strings have length 35+175=210 cm.

The total length of string needed for 17 identical decirative bottes is $210\cdot 17=3570$ cm that is 35.7 m.

Answer: 35.7 m

Answer 2

The total length of string to decorate 17 identical decorative bottle is 3570 cm or 35.7 m

Further Explanation

String A is 35 cm long

String B is 5 x string A

Question

Total length of string needed?

String A = 35

String B = 5 x string A

             = 5 x 35

             = 175 cm

$\boxed {The total length = String A + String B\ }$

= 35 cm + 175 cm

= 210 cm

The total length to decorate one bottle is 210 cm

To decorate 17 identical bottles, it would need:

$\boxed { 210 \times\ 17 = 3570\ }$

Here is to solve the multiplication in standard algorithm method:

  21

  17  x

147

 21     +

357

then adding the zero = 3570

To simplify the multiplication we just do the two digit numbers and then adding the zero later in the answer,

So the total string needed for all the decorative bottle is 3570 cm or 35.7 m
