You have a square that has a side length of 1 centimeter. Each minute, 2 centimeters are added to the side length. After 70 minutes, what will be the difference between the area of the last square and the area of the initial square in square centimeters (do not include the units in your answer)?

Initial square area    1 cm  x   1 cm =   1 cm2

  After  70 minutes side is   1 + 2(70) = 141 cm      Last square area = 141 x 141 cm = 19,881 cm2

 

    You can calculate the difference..........
