The first volume of the fifth grade mathematics book for primary schools, the sixth question on page 55 of Beijing Normal University Press, has a parallelogram grass with a length of 8 meters and a width of 1 meter in the middle. First calculate the area of parallelogram, then calculate the area of the middle rectangular path, and finally subtract the area of rectangle from the area of parallelogram.

Parallelogram: 25× 8 = 200m2

Rectangular: 8× 1=8 square meters

Grassland area = 200-8 = 192m2.
