Best ResponseYou've already chosen the best response.2ok, now we use the formula for perimeter perimeter = 68 = 2(L+W), with me so far?

Best ResponseYou've already chosen the best response.2good, now we can rewrite our formula we know that W = L  6, so we can replace "W" with "L6" whenever we see it perimeter = 2(L+W) = 2(L+L6), understand so far?

Best ResponseYou've already chosen the best response.2good, now let's put L + L together to get 2L perimeter = 2(2L6) = 68 know how to solve for L now?
