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

its the perimeter i need to find

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

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

i combined the liked terms and i got 3m+6
 one year ago

spidergirl51Best ResponseYou've already chosen the best response.0
then i divide it by 3 m on both sides which get m=2

psi9epsilonBest ResponseYou've already chosen the best response.0
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
