Question

the length of a rectangular field is 10m more than its breadth. the cost of fencing the field at a rate of ₹30 per metre is equal to 105 times the length of the field. find the length and breadth of the field
​

Answer 1

Answer:

Let the breadth be x, then length =x+10

Perimeter =2(l+b)

⇒52=2(x+x+10)

⇒26=2x+10

⇒16=2x

So x=8

x+10=18

Length, Breadth =18,8.
