How 190 marla would be designed for plotting

I have 190 marla area in square shape. A 20 feet road is touching it from one side. I want to make plots leaving 15 feet road for accessibility. What would be better design or model to accommodate 3-5 marla plots.

Main road can be 30 feet and internal roads can be 15 feet. What you say experts…

Please mention the dimensions of the plot.
