Answer:

1134.08 m²

Step-by-step explanation:

To calculate the area of grass, subtract the area of the polygon from the area of the large green rectangle.

area of a triangle = 1/2 x base x height

area of a rectangle = width x length

area of large (green) rectangle = 40 x 36 = 1440 m²

area of regular 8-sided polygon = 4 triangles + 2 small rectangles + large rectangle

= 4(1/2 x 5.6 x 5.6) + 2(8 x 5.6) + (8 x 19.2) = 305.92 m²

Therefore, area of grass = 1440 - 305.92 = 1134.08 m²
