Answer:
0.84 km=84*1000/100=840m
Length of rectangular park,
Breadth of rectangle=2b
Perimeter=2(3b)=840
b=840/6=140m
Area=280*140
39200m^2
Answer:
Step-by-step explanation:
Let the breadth of a rectangular park be x
Then it's length=2x
Perimeter =0.84 km =840meter
Now,
2(2x + x) =840 meter
4x+2x=840 meter
6x=840meter
x=840 meter/6
x=140 meter
Thus, breadth=140meter and length=2×140meter=280meter
Then,
Area of the rectangular park= l×b
=140meter × 280meter
=39200meter^2
