A traffic sign is in the shape of a square with each side equal to 20 inches. What is the area of the sign in square inches?(1 point)
To find the area of a square, you multiply the length of one side by itself. In this case, the side length is 20 inches.
Area = side length * side length = 20 inches * 20 inches = 400 square inches.
Therefore, the area of the traffic sign is 400 square inches.
