Question

The perimeter of ABCD is 66, and line DC is twice as long as line CB. How long is line AB? Pleasee help :)

Answer 1

Is this a rectangle?

Answer 2

i think that one of the lines is missing line AD

Answer 3

If we assume a rectangle or kite, or parralellogram, which I think is the only way to solve the problem, then 66 is split between four sides like this:

Answer 4

There are 6 A's that add up to 66, so set up an equation...

Answer 5

Then you have to think about whether AB is a long side or a short side.
