Answer:

33/ 8 m

Step-by-step explanation:

length of rod =yellow portion +green portion+ WHITE portion

1/8+1/2+7/2=length of rod

1+4+28/8=33/8= length of rod

Answer 2

Answer:

8m

Step-by-step explanation:

Answer:

8m

Step-by-step explanation:

Let the lenght if the rod be = x

Part of rod which is yellow = 1/8*x = x/8

Part which is green = 1/2*x - 7x/8 = 7x/16

Remaining part of rod = x - ( x/8 + 7x/16)

= x - 9x/16 = 7x/16

According to question,

7x/16 = 7/2

So, x = 8
