To the nearest tenth, which is the perimeter of △ABC

My best guess is 24

Step-by-step explanation:

idk if this is right or not, but the triangle could be a 3 4 5 right triangle.

3 x 2 = 6

4 x 2 = 8

5 x 2 = 10.

6 + 8 + 10 = 24

this is the best answer i got. Don't know if it's going to help...

so, converting firstly the mixed fractions to improper fractions and then "adding".

my apex says that it is false
