50.24 multiply 3.14 by 16
Whats the following 3 lol thats where your information is from maybe write it down?
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
Just add. 6.5+12.3= 18.8 then subtract 20-18.8= 1.2. She needs 1.2 mores yards
