Answer:
one side is 4 and the other two sides are 12
Step-by-step explanation:
let the 3rd side be x.
So the 1st and 2nd sides will be 3x.
Perimeter is the sum of all sides so 3x+3x+x=28
∴ 7x=28
if u bring 7 to left hand side x=28/7
∴x= 4
so one side is 4 and the other two are 12
proof: 4+12+12=28
hope this helps
