Answer:

Amount=1600

Rate= 25

Perimeter=1600/25=64m

length=20m

2(l+b)=64

l+b=64/2

20+b=32

b=32-20

breadth=12m

Area=l*b=20*12= 240m^2

Total cost = 1600

rate of fence= 25

Then area of rectangular park = Total cost/rate of fence

= 1600/ 25

=64m^2

Therefore, area = 64m^2

length of the park= 20 m

Breadth=?

Area of rectangle= length*Breadth

64 = 20* Breadth

64/20 = breadth

3.2 m = breadth

Therefore breadth is 3.2 m

So perimeter of the rectangular park =

2(length+breadth)

2(20+3.2)

=46.4 m

So we found breadth which is 3.2 m

perimeter which is 46.4 m

Area which is 64 meter

SQUARE
