Question

Rubina has 18 metres of ribbon. She cuts it into two pieces in such a way that one piece is 4 metres longer than the other. Find the length of the shorter piece.
​

Answer 1

Answer:

7 meter

Step-by-step explanation:

Total length = 18m

Let 1st piece length = x

Then,

2nd piece length = x + 4

1st piece length + 2nd piece length = Total length

x + x + 4 = 18

2x + 4 = 18

2x = 18 - 4

2x = 14

x = 7m.

Second piece length = x + 4

= 7 + 4

= 11m
