P = 2L + 2W this is the formula right?
undeadknight26 (undeadknight26):
so lets put in what we know... 90 = 2 x 15 + 2w 90 = 30 + 2w -30 -30 60 = 2w /2 /2 30 = w
undeadknight26 (undeadknight26):
right?
undeadknight26 (undeadknight26):
and the first one is 2 because you would do the opposite of what the regular equation is... such as 5 + a = 7 you would do 5 - 7 = a
undeadknight26 (undeadknight26):
