1 Pabitra had 19×2/7 of petrol in the fuel tank of his vehicle at the start of a journey. During the journey, 13×1/2.of petrol was
consumed. What fraction of the initial petrol was left in the fuel tank after the journey?
​

Answer 1

Answer:

Area of original garden =90×75=6750 m

2

After path is added around rectangle, new length =90+2×5=100 m

New breadth =75+2×5=85 m

Area of rectangle with path =100×85=8500 m

2

So,

Area of path = Area of rectangle with path − Area of rectangle without path

Area of path =8500−6750

=1750 m
