Best ResponseYou've already chosen the best response.0So if sides are m, and m+3 and m+3 sum is 3m+6

Best ResponseYou've already chosen the best response.0yes very sure, do you want to find the perimeter or AREA ?, REMEBER PERIMETER IS ALWAYS the SUM of all sides

Best ResponseYou've already chosen the best response.0so my formula ((m+3)*2+m)=P works too :)

Best ResponseYou've already chosen the best response.0yes so thats correct, perimeter is m+ m+3 + m+3 = 3m+6

Best ResponseYou've already chosen the best response.0i combined the liked terms and i got 3m+6

Best ResponseYou've already chosen the best response.0then i divide it by 3 m on both sides which get m=2

Best ResponseYou've already chosen the best response.0why do you want to divide, you just need the perimeter , P= 3m+6 are you supposed to find the value of m, and do you have the value of perimeter given?

Best ResponseYou've already chosen the best response.0spider, "m" is a variable  it has no number except the one you, or your textbook or teacher give it, if they didn't give you a number for Perimeter variable, or m, then it's just m
