The area of the metal sheet required to make this square-shaped traffic sign is x² + 2x + 1. Then the correct option is A.
It is a polygon that has four sides. The sum of the internal angle is 360 degrees. In a square, opposite sides are parallel and all sides are equal and each angle is 90 degrees. And its diagonals are also equal and intersect at mid-point at right-angle.
A square-shaped traffic sign is shown with the length of one side labeled as x plus 1.
Side of square = x + 1
Then the area of the square will be
Area = (side of square)²
Area = (x + 1)²
Area = x² + 2x + 1
Thus, the area of the metal sheet required to make this square-shaped traffic sign is x² + 2x + 1. Then the correct option is A.
