    The lengths of each part of the rectangle are correctly labelled. Similarly, the areas of all the parts are correctly written.

    The statement (x-9)(x-9)=.... is not clear.
    Please edit this post and key in at the post area.

    Also, you are to take a picture to show how the answer can be worked out using the FOIL Method.
    Take a picture of that and upload in this same post.

    BTW, use pen to write.
