Answer:
2. 9 cm
Step-by-step explanation:
The wire having length 30 cm is formed into rectangle.
This means the perimeter of rectangle should be equal to 30 cm.
So given that perimeter of rectangle is 2(length+Breadth).
Therefore, 30 = 2(Length + Width)
We have width = 6 cm.
30 = 2(Length + 6)
30 = 2* Length + 12
30 -12 = 2 *Length
18 = 2 * Length
Length = 9 cm.
