Question

cost of fencing a rectangle field at RS.50 per metre is RS.2400.if length=24 cm.find breadth

Answer 1

Area of rectangle =length × breadth

Answer 2

Answer:

Cost of fencing ₹2400

Then perimeter of rectangle = 2400/50 = 48m

Perimeter = 2(l+b)

48 = 2(24+b)

48 = 48 + 2b

2b = 0

b = 0

Then it must be a straight line.
