Help please

I have a field total 25740 sq mtrs

I need to divide it into 7 plots

Plots 1 to 4 are to be equal in surface area

Plots 1 & 2 combined or 4 & 5 combined are obviously the same.

However plots 5, 6 & 7 are equal in surface area also and equate to the total area of plots 1 & 2 combined or 3 & 4 combined.

What is the actual individual surface area of plots 1,2 & 3 and 4,5,6 & 7

Thank you

 

I think that you have made a mistake.

1=2=3=4

1+2=4+5

means

1=2=3=4=5

but 5=6=7

so

1=2=3=4=5=6=7

so

5+6+7 cannot equal 3+4
