As shown in the figure, the square ABCD and an isosceles right triangle EFG (EF = EG) are placed on the same straight line. Now the triangle does not move, and the square moves to the right at a speed of 2 cm / s along the straight line at a constant speed? (1) At 10 seconds______ (2) in the 11th second______ (3) at the 13th second______ Square centimeter; 4______ Second, the area of the overlap is 18 square centimeters______ Second, the area of the overlap is 34 square centimeters

(1) (10 × 2-16) × (10 × 2-16) / - 2, = (20-16) × (20-16) / - 2, = 4 × 4 / 2, = 8 (square centimeter); answer: in the 10th second, 8 square centimeter. (2) (11 × 2-16) × (11 × 2-16) / - 2, = (22-16) × (22-16) / - 2, = 6 × 6 / 2, = 18 (square centimeter)
