Best answer

Let the breadth of the rectangular park be b.

∴ Length of the rectangular park = l = 2b

Perimeter = 840 m

\(\Rightarrow\) 840 = 2(l + b)

\(\Rightarrow\) 840 = 2(2b + b)

\(\Rightarrow\) 840 = 2(3b)

\(\Rightarrow\) 840 = 6b

\(\Rightarrow\) b = 140 m

Thus, we have:

l = 2b

= 2 x 140

= 280 m

Area = l x b

= 280 x 140

= 39200 m2
