    Given:

    square shaped traffic sign. side measure of 8x - 2

    A square has 4 equal sides. To find the area of a square, simply square the measure of 1 side.

    Area of a square = a²

    A = (8x-2) ²

    A = (8x-2) (8x-2)

    A = 8x (8x-2) - 2 (8x-2)

    A = 64x² - 16x - 16x + 4

    A = 64x² - 32x + 4
