Area of rectangular lawn = l \times b = 10 \times 5 = 50 m^2

Area of flower bed = \pi r^2 = 3.14 \times 4 = 12.56 m^2

Area of the lawn excluding the area of the flower bed = Area of rectangular lawn - Area of flower bed

= 50 - 12.56 = 37.44 \ m^2

Therefore, the area of the lawn excluding the area of the flower bed is 37.44 \ m^2
