You are in trouble. Listen to me!
First of all, please distinguish Mu from mu
1 hectare = 100 square meters
1 mu = 666.67 square meters
secondly
1 ha = 10000 M2
So, as the title
7000 Mu = 0.7 * 10000 * 666.67 M2 = 0.7 * 666.67 ha

The unit conversion between meter and hectare is not clear

10000 M2 = 1 ha

Unit conversion: 5 ha 40 M2 = () ha

5 ha 40 M2 = (5.004) ha
