Answer:
or D
Step-by-step explanation:
First, look at the ratio. And out of 2&3&4, 2 is the smallest. So, change the 2 to 15, 3 to X, 4 to Y. Like this down below
15:X:Y
Now, if 2=15, 1=15÷2, which is 7.5
If one is 7.5, the X=3×7.5=22.5
Y=4×7.5=23
Add them all up, 15+22.5+23=60.5
The perimeter is 60.5
