8 meters increased by 25%

10 meters

Explanation:
First, we will compute 25% of 8 as follows:
25% of 8 = 25% * 8
= 0.25 * 8
= 2

Now, 8 increased by 25% of 8 means that we will add the 25% of the 8 that we computed to the 8 we have.
Therefore:
8 increased by 25% = 8 + 25% of 8
= 8 + 2
= 10 meters

Hope this helps :)
