Answer:
42 %
Step-by-step explanation:
the initial band length is 60 cm
increased length is 85 cm
changed length = 85 cm - 60 cm = 25 cm
percentage increase in length =( changed length / initial length ) x 100
= ( 25 cm / 60 cm ) x 100
= 25 cm x 100 / 60 cm
= 25 x 10 / 6
= 25 x 5 / 3
= 125/ 3
= 41.66
