I will give u brainliest and 5 star and thanks if its correct

1. the side length of the square is 3 when its perimeter is 12.

2. (20/21, 5/21)

Step-by-step explanation:

2. 20/21 ÷ 4 = 20/21 × 1/4 = 5/21(the side length of the square with the given perimeter of 20/21)

=> (20/21, 5/21)

answer: f true

step-by-step explanation:

2 over 5

step-by-step explanation:

the 2: 3 ratio is the length of the ac segment to the cb segment total length. this implies that the ratio between segment ac length and segment ab length is 2: 5. point c is 2/5 from a to b, so the required fraction is 2/5.
