ezrunner, here it is:

given: triangle's perimeter = rectangle's perimeter

this will be the mother equation:

a + b + c [triangle] = 2w + 2l [rectangle]

x + (x+1) + (x+2) = 2(x+1) + 2(x-3)

3x + 3 = 2x + 2 + 2x - 6

3x + 3 = 4x - 4

x = 7

?

maybe you can help me now since i've been trying to figure my IMAPworkemail to get pushed to my 8320. haha
