Hi
First dont panic. this one is pretty easy.
you known that the perimeter is the addition of every sides of a figure.
you have the total perimeter : 84.6
so now you just have to withdraw every side you have to the total , and the missing measure will be the result.
have a try ! you can make it.
3m-10=2(4m-5)
3m-10=8m-10
3m-8m=-10+10
-5m=0
m=0
4x + 10 = 2x + 20
4x - 2x = 20 - 10
2x = 10
x = 5
