find the area

In this problem, you are asked to solve the area of a trapezoid. The formula in finding the area of a trapezoid is:

A = [(a + b)/2] x h

Where a = base 1

             b = base 2

             h = height

Substituting the given measurements to the formula:

A = [(6.9 km + 2.7 km)/2] x 2.2 km

A = (9.6 km/2) x 2.2 km

A = 4.8 km x 2.2 km

A = 10.56 km^2

Therefore, the area is 10.56 square kilometers.

step-by-step explanation:

the answer is a

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.
