Question

THE COST OF FENCING A RECTANGULAR AT THE RATE OF Rs 7.50 IS Rs 600. THE LENGTH OF THE PARK IS 24m. FIND THE BREADTH.

Answer 1

Cost of fencing the rectangular field = Rs. 600

Rate of fencing the field = Rs. 7.50 per m

Therefore, perimeter of the field = Cost of fencing / Rate of fencing = 600 / 7.50 = 80 m

Now, length of the field = 24 m
perimeter = 2(length+breadth)

Therefore,
breadth of the field = Perimeter / 2 – Length = 80 / 2- 24 = 16 m
