Question

length of rectangle is three times its breadth its perimeter is 64m.find cost of harvesting it at the rate if rs 56 per m².

Answer 1

Answer:

Rs.10752

Step-by-step explanation:

length=l   breadth=b

l=3*b

perimeter= 2(b+3b)

        64   =2(4b)          

         64   = 8b

           8   =b

then length= 3*8

                   = 24m

area= 24*8

      =  192m^2

1m^2=Rs.56

192m^2=  56*192

             =Rs.10752      

Answer 2

Let l= 3x and b= x

64= 2(3x+x)

64=8x

x=8

L= 3*8=24. B=8

Cost of harvesting = 8*24*56

=115584m^2
