Answer: 10 meters
=====================================
Explanation:
Take 25% of 8 to get 0.25*8 = 2
The length increased by 2 meters, meaning that the final length is
8+2 = 10
-----
Alternatively, multiply 1.25 by 8 to get 1.25*8 = 10
The 1.25 multiplier refers to 100% + 25% = 1.00 + 0.25 = 1.25
So we start with 100% (the original value 8) and then add on 25% of that (2) to get the final answer 10
