The perimeter of the square is 28 cm. What will be the area of the square if its side is lengthened by 2 cm?

Let’s solve the task of actions with explanations. 1) 28: 4 = 7 centimeters – the side of the square (Since in a square four sides are equal to each other, and the perimeter is the sum of all the lengths of the sides of the figures); 2) 7 + 2 = 9 centimeters – the length of the side of the square, when the side of the square was increased by 2 centimeters; 3) 9 * 9 = 81 square centimeters – the area of a square with a side of 9 centimeters (Since the area of a square is found by raising its side to a square). Answer: 81 centimeters square.
