Question

the breadth of a rectangular field is twice its length if the area of a field is 1058 square find the cost of fencing its rupees 35 per metre

Answer 1

Answer:

Rs.4830 Please bro mark me as the brainliest  for the pain ive taken to write the whole explanation

Step-by-step explanation:

Let length be l

therefore breadth =2l

area of rect= lX2l

1058=2l²

l²=529

l=23

therefore breadth = 2l = 46

Perimeter= 2(l+b)

                 =2(23+46)

                  =2X 69

                  =138

Cost=138X 35

       = 4830
