Answer 1

To find the area of the playing field, we need to calculate the area of the original rectangle and then subtract the area of the rectangular section that was removed.

1. Calculate the area of the original rectangle: \[ \text{Area of original rectangle} = \text{length} \times \text{width} = 10 , \text{m} \times 6 , \text{m} = 60 , \text{square meters} \]

2. Calculate the area of the removed rectangle: The remaining length and width given for the playing field are 8 meters and 4 meters, respectively. Therefore, the dimensions of the area that was removed are:

   • Removed length = 10 m - 8 m = 2 m
   • Removed width = 6 m - 4 m = 2 m

   Now calculate the area of the removed rectangle: \[ \text{Area of removed rectangle} = \text{length} \times \text{width} = 2 , \text{m} \times 2 , \text{m} = 4 , \text{square meters} \]

3. Calculate the area of the playing field: \[ \text{Area of playing field} = \text{Area of original rectangle} - \text{Area of removed rectangle} = 60 , \text{square meters} - 4 , \text{square meters} = 56 , \text{square meters} \]

So, the area of the playing field is 56 square meters.
