Question

If it costs Rs 1600 to fence a rectangular park of length 20 m at the rate of Rs 25 per m², find the breadth of the park and its perimeter. Also, find the area of the field.

Answer 1

Total cost = 1600

Rate of fence= 25

Then Area of rectangular park = Total cost /Rate of fence

                                                =1600/25

                                                 =64 m^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)

                                                             = 2*23.2

                                                             =46.4 m

So we found Breadth which is 3.2 m

                      Perimeter which is 46.4 m

                       Area which is 64 metre square

I hope it helped you

Answer 2

Answer:

Costs 25Rs for each m2

For 1600Rs , area will be 160025=64m2

If length is 20m, then breadth = Arealength=6420=165m=3.2m

Perimeter = 2(length + breadth) = 2(20+3.2)=46.4m
