Question

the cost of fencing a rectangular field at rupees 18 per meter is rupees 1980. if the width of the field is 23m , find its lenght ​

Answer 1

Step-by-step explanation:

perimeter of rectangle =2(l+b)

1980=2(l+23)

1980/2=l+23

990=l+23

990-23=l

967=l

perimeter =2(l+b)

=2(967+23)

=2(990)

=1980m

cost of per meter is =18rupees

cost of 1980m is =18^1980

=35640 rupees
