Question

Which expression is equivalent to the area of metal sheet required to make this square-shaped traffic sign? A square shaped traffic sign is shown with length of one side labeled as 8x minus 2.

Answer 1

64x2 − 32x + 4

Explanation:

Answer 2

For a square, with a length of 8x-2, the height must be the same in order for this to be a "square". The area of a square is the height multiplied by the length, so (8x-2)^2 will be your answer. Simplified it will be 64x^2 - 16x + 4.
