Answer:
The longest length of carpet is 160 cm.
Step-by-step explanation:
Given that the total ratio(units) of the carpet is 9(2+3+4). So first, you have to find the length of carpet in 1 unit :
[tex]9 \: units = 360 \: cm[/tex]
[tex]1 \: unit = 360cm \div 9[/tex]
[tex]1 \: unit = 40 \: cm[/tex]
Next, you have to find the length of carpet in 4 ratio as the question wants the longest length :
[tex]4 \: units = 40 \: cm \times 4[/tex]
[tex]4 \: units = 160 \: cm[/tex]
