Explanation:

The intensity of irrigation is calculated as the total area irrigated in all crops in a year expressed as a percentage of the total cultivable command area.

For this calculation, it's important to note that if an area is used multiple times a year for separate crops it's counted each time (Thus it is possible to have irrigation intensities more than 100%).

Assuming this is the only crop, the intensity of irrigation for Rabi crop in this specific scenario would be:

= [100 hectares (Area under Rabi crop) / 150 hectares (Cultivable command area)] × 100

= 66.67%

So, in this case, the intensity of irrigation of the Rabi crop is 66.67%.
