Jane wants to plant grass in het backyard. Her backyard is in the shape of a rectangle. Its length is 32 feet and its width is 21 feet. Suppose each pack of seed covers 12 square feet. How many packs of seed she need to cover the backyard

56 pack

Step-by-step explanation:

Length of backyard(L)=32feet

Width of backyard(W)=21feet

Area of backyard(A)=?

A=32x21

A=672 square feet

Each pack of seed cover 12 square feet

Therefore 672/12pack will be needed to cover the whole area of the backyard

672/12=56 pack will be needed

41*67/2=1373.5

step-by-step explanation:

i just used a calculator

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.
