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? and how do you get the answer

To find the area of a square, you simply multiply the length of one side by itself.

In this case, the length of one side of the traffic sign is 20 inches.

So, to find the area of the sign, you would use the formula:

Area = Side x Side

Area = 20 inches x 20 inches
Area = 400 square inches

Therefore, the area of the traffic sign is 400 square inches.

why 20x 20

To find the area of a square, you multiply the length of one side by itself (the side squared). In this case, you have a square traffic sign with all sides equal to 20 inches. The formula for the area of a square is side x side, which is essentially the same as side squared. This is why we multiply 20 inches by 20 inches to find the area of the square traffic sign.
