Answer 1

6

given

cost- 7rs 12p

length of area-45m

breadth of area-30m

first find the area i.e. 45x30 =1350sq m

secondly multiply the cost into area

=7.12x1350

=9612 rupees

7

first convert the length and breadth to either cm or m (I prefer m)

length=34.2m

breadth=16.3m

area=34.2x16.3

=557.46sqm

cost of fencing=557.46x40

=22298.4rs

cost of turfing=557.46x21

=11706.66rs
