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 [tex] 210\cdot 17=3570 [/tex] cm that is 35.7 m.
Answer: 35.7 m
The total length of string to decorate 17 identical decorative bottle is 3570 cm or 35.7 m
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
[tex]\boxed {The total length = String A + String B\ }[/tex]
= 35 cm + 175 cm
= 210 cm
The total length to decorate one bottle is 210 cm
To decorate 17 identical bottles, it would need:
[tex]\boxed { 210 \times\ 17 = 3570\ }[/tex]
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
