Best way to water the backyard lawn?

My backyard lawn (white area) is in this L-shape and I was thinking of laying a drip hose (green line) roughly like the picture above. But since I’m a complete amateur I thought to validate the idea here before learning the hard way.

I want to minimise cost and maximise coverage. I’m not looking at either an in ground irrigation system or a cheap sprinkler that would make a mess and waste water. I won’t be irritating every week, but only when/if the lawn is struggling.

Is this a good idea? Are there better options I should consider, other than just watering by myself?

What brand or types of hoses should I use?

(I calculated 62m length to cover the area spacing it 1m between lines)
