    Answer:

    32 yards, 128 square yards.

    Step-by-step explanation:

    Given:

    Length of rectangular garden = 16 yards

    Breadth of rectangular garden = 8 yards

    One of the long sides runs along a​ wall.

    Mary wishes to use fencing to finish enclosing the garden.

    To find:

    How much fencing does she​ need ?

    How many square yards does she have for planting her​ garden means area of rectangular garden = ?

    Solution:

    To find that how much fencing she need we must know that we have three side to fence because at one side there is a wall so no need to fence and we have one length and two breadth.

    She need for fencing = perimeter of rectangular garden – one side length  

                                       = 2(length + breadth) - 16

                                       = 2(16+8) - 16\\

                                       = 2(24) - 16

                                       = 48 - 16 = 32 yards

    Thus, She need 32  yards for fencing the rectangular garden.

    Now, we will find How many square yards she have for planting her​ garden.

    Area of rectangular garden = length\times bredth

                                                  = 16\times8 = 128

    Thus, she have 128 square yards for planting her​ garden.
