Afarmer has one square mile of land. if he divides his land into square fields that are 1 - 2 mile long and 1 - 2 mile wide, how many fields will he have?

a field that is ½ by ½ has an area of ½*½ or namely ¼.

now, the farmer has 1 m² of land, if he divides it in ½ by ½ plots, how many of those plots will there be? namely how many times ¼ goes into 1?

c. 1,233 miles

answer: the proof is mentioned below.

step-by-step explanation:

since, given:   lines bc = ef

prove:   lines ac > ef

          statements                                           reason

1. bc=ef                                           1. given

2. ac= ab+bc                                 2. because b is the point between the  

                                                            line segment ac

3.   ac > bc                                       3. because if a line segment is equal to

                                                          the sum of two line segments then it is

                                                          always greater then each of these

                                                          individual line segments

4. ac > ef                                         4. by equality property.
