Question

The total cost of building a wall around a rectangular fields is ₹680 at the rate of ₹ 8.50 per meter. If the length of the field is 25 m ,what is breadth of the field?​

Answer 1

the breath of the field is 15.

Answer 2

680 divided by 8.5= 80m

If the perimeter of the field is 80 m then :-

p = l * b

80 = length * 25

Length = 80 divided by 25

Length = 3.2


Verification:-

P = l * b

P = 25 * 3.2

P = 80m

So therefore the breadth of the filed is 3.2m.
