An area of 2 square meters of rectangular paper, fold three times after the small rectangular area is () square meters A. 12B. 13C. 14D. 18

2 × 12 × 12 = 14 (M2), so C

Fold a 2 / 3 decimeter square paper in half to get a rectangle. The circumference of the rectangle is () and the area is ()

Perimeter: 1 / 36 decimeter
Area: 1 / 72 square decimeter

A square piece of paper, its side length is 67 decimeters, fold it into a rectangle, the circumference of the rectangle is______ Decimeter. What's the area of a rectangle______ Square decimeter

The perimeter is (67 + 67 × 12) × 2, = 97 × 2, = 187 (decimeter); the area is: 67 × (67 × 12) = 1849 (square decimeter). Answer: the perimeter of a rectangle is 187 decimeter, and the area is 1849 square decimeter
