A farmer has 70 meters of fencing to enclose a rectangular garden that has one side of the garden against a barn. Let l represent the length of the rectangular garden (in meters). (Notice that the 90 meters of fencing is needed for only 3 sides of the garden.) Suppose the length of the garden is 30 meters ( l = 30 ). What is the width of the garden?What is the area of the garden?

This is B and C

Step-by-step explanation:

(B) L + 2w = 70

     2w = 70 - L

        w = (70 - L)/2

(C)    Area as a function of L:

         Area = length * width

                  =  L * (70-L)/2

the answer is (4,3)

since the rule for r0, 90º is (-y,x) and it was already applied to form the image, all you have to do is reverse the answer using this formula.
