    PERIMETER is sum OF ALL SIDES

    So if sides are m, and m+3 and m+3 sum is 3m+6

    yes very sure, do you want to find the perimeter or AREA ?, REMEBER PERIMETER IS ALWAYS the SUM of all sides

    so my formula ((m+3)*2+m)=P works too :)

    yes so thats correct, perimeter is m+ m+3 + m+3 = 3m+6

    then i divide it by 3 m on both sides which get m=2

    why 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?

    spider, "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
