​

Answer 1

Answer:

=89.25 km

Step-by-step explanation:

Method:-1

According to the question main line is 5% more than cord line. So, If the cord line is 100 km ,the main line will be 105 km .          

       Cord Line (Km)                             Main Line (Km)

         100                                                          105

          85                                                            ?

So cord line =(85*105)/100=89.25 km

Method:-2 According to the question main line is 5% more than cord line. So, If the cord line is 100% km ,the main line will be 105%.

SO, 105% of chord line(85) =(85*105)/100=89.25 km
