Grasshopper Irregular or unequal polygon

I’m very new in grasshopper and im trying to use grasshopper to create a polygon with edges of 2 different alternating lengths. Could anyone help me with this? Thanks.

Be easier with a chamfer tool. Just update the Point Groups distance if it starts failing.
