Question

A rope was cut into three shorter pieces in a ratio 3:7:4. The length of the longest piece was 12 meters more than the length of the shortest piece. (a)What was the length of the longest piece?

Answer 1

Answer:

length of the longest piece=21 cm.

Step-by-step explanation:

Ratio= 3:7:4.

Let the ratio be x.

Longest piece=7x.

According to the question,

Therefore, 7x=12+3x

=> 7x-3x=12

=>4x=12

=>x=12/4

=>x=3

Therefore, 7x=7*3=21 m (Ans)
