the length and breadth of a playground is 62m 60 cm and 25m and 40cm respectively. Find the cost of turfing at 2.5.rs per sq. meter. How long man can take to go three times around the field if he walks at rate of 2meter per second

step by step,
length = 62m
breadth = 60m
area = L X B
= 62 X 60
= 3720 m square
cost = 2.5 X 3720
= Rs 9300
time = perimeter/2
= 2(62+60)/2
= 2(122)/2
= 244/2
= 122 second
2) length = 25m
breadth = 40m
area = l X b
= 25 X 40
= 1000 m square
cost = 1000 X 2.5
= Rs 2500
time = perimeter /2
= 2(25+40)/2
= 65 second
hence prove
I hope this will help you...

= 3720 m square
cost = 2.5 X 3720
= Rs 9300
time = perimeter/2
= 2(62+60)/2
= 2(122)/2
= 244/2
= 122 second
2) length = 25m
breadth = 40m
area = l X b
= 25 X 40
= 1000 m square
cost = 1000 X 2.5
= Rs 2500
