A square field that is 1/4 mile long and 1/4 mile wide has area
So, to know how many of these fields fit in the biggest field, you have to divide their areas:
So, if the farmer divides his land into square fields that are 1/4 mile long and 1/4 mile wide, he will have 16 of these smaller fields.
First is 7 second is 8 third is 3
W + 4 > -12
Subtract 4 from both sides
w = -16
