Question

The length and breadth of a rectangular field are in the ratio 5:3. The area of the field is 2160 sq. m. If a fench is to be made at the rate of Rs.350 per metre, how much it will cost?

Answer 1

so lenght is 60 and breadth is 36 that is equal to 196 perimeter so it is 196 x 360 ruppees and that equals to 70560 ruppees.

Answer 2

Answer:

length=60

breadth=36

perimeter=192

cost of fencing=192*350

                         =67200

Step-by-step explanation:

length=5x

breadth=3x

area= l*b=2160

       =50x+30x=2160/180

                        =180

length=5x=5*12=60

breadth=3x=3*12=36

perimeter=2(l+b)

                =2(60+36)

                =2*96

                =192

cost of fencing=192*350

                        =67200
