The trapezoid's upper bottom is increased by 3 cm, and the lower bottom is increased by 2.5 cm to form a square with a circumference of 36 cm

The trapezoid's upper bottom is increased by 3 cm, and the lower bottom is increased by 2.5 cm to form a square with a circumference of 36 cm

The side length of the square is: 36 △ 4 = 9 (CM), so the area of the trapezoid is: (9-3 + 9-2.5) × 9 △ 2 = 12.5 × 9 △ 2 = 56.25 (square cm). A: the area of the trapezoid is 56.25 square cm
