Question

the ratio of the length to breadth of a lawn is 3 ratio 5 if the cost rupees 32208 @ rupees 2 m what would be the cost of developing the lawn @ rupees 10 per square metre

Answer 1

Answer:

₹80520

Step-by-step explanation:

Let, length be 3x

  breadth be 5x

Now,

2(3x+5x)*2=32208

2*8x*2=32208

x=32208/32

x=1006.5

now,

Length=3*1006.5

          =3019.5

Breadth=5*1006.5

             =5032.5

Now,

Total cost= ₹10*2(3019.5+5032.5)

                =₹80520
