Question

The cost of fencing a rectangular park of length 300m 500cm and breadth 200m 500cm at the rate of Rs. 10 per meter is?

Answer 1

length of rectangular park = 300m 500cm = 305m
breadth of rectangular park = 200m 500cm = 205m
perimeter of the rectangular park = 2(l+b)
                                                     = 2(305 +205)
                                                     = 2(510)
                                                     = 1020m
cost of fencing per meter= rs.10
cast of fencing per 1002m= 10×1020
                                          = rs.10200

Answer 2

Length=305m=30500cm
Breadth=205m=20500cm
Perimeter of rectangle=2(L+B)

2(30500+20500)
2(51000)
=102000cm

Converting into metre
=1020m

Cost of fencing .......10/m
So,

1020*10
:·Total cost=10200 ...rupees...
