Answer:
1. The length of the floor is = 60 m.
The breadth of the floor is = 50 m.
The perimeter will be = 2*(60+50) m.
= 2*110 m.
= 220 m.
ans: The perimeter of the floor is 220 m.
2. 15 minutes in seconds,
1 minute = 60 seconds
15 minutes = (60*15) seconds
= 900 seconds
(900+20) seconds
= 920 seconds
3. Ram had money = 4500 Rs.
he deposited money this month = 960.25 Rs.
now, he has money = (4500-960.25) Rs.
= 3539.75 Rs.
