suppose the farmer buys another 1/2 square mile of land and divides all his land into square fields 1/4 mile long and 1/4 mile wide. how many fields will he have?

1/4 mile long and 1/4 mile wide. so he had 16 fields in the beginningng

1/8

1/2+1/4+1/4=1

How much land did he have in the beginning?

You can work it algebraically or you could draw a diagram.

I see 4 more fields.

16 fields?
