A playground which is 200m long and 40m wide is to be faced with wire. How much wire is needed?

Question

Answer

If you  know that in rectangle in any regular polygon. long=length, wide= breadth.so long=length=200mwide=breadth=40mif you are fencing the land so you fence at boundaries only not in full land.so to know the boundaries we need to take it's perimeter.Perimeter of rectangle= 2 x [length+breadth]                                   = 2 x [200+40]                                   = 2 x 240                                   = 480 metertherefore to fence the rectangular land of 200m long and 40m wide is 480 meter.

Answer

Understanding the Playground Dimensions
The playground has specific dimensions that need to be considered for fencing. The length and width are:
- Length: 200 meters
- Width: 40 meters
Calculating the Perimeter
To determine how much wire is needed, we first need to calculate the perimeter of the playground. The formula for the perimeter (P) of a rectangle is:
P = 2 × (Length + Width)
We will use the dimensions given:
- Length = 200m
- Width = 40m
Step-by-Step Calculation
1. Add Length and Width:
200m + 40m = 240m
2. Multiply by 2:
2 × 240m = 480m
Total Wire Needed
The total amount of wire required to fence the playground is:
- 480 meters of wire
Conclusion
To adequately face the playground with wire fencing, you will need a total of 480 meters of wire. This ensures that the entire perimeter is enclosed, providing a safe and secure play area.
