1.	rectangular field is 72 m by 58 m. Keya walks around it at the rate of 3 km per hourHow longwill she take to make 3 rounds?
Answer» Length of one round (perimeter of rectangle) = 2 (72 + 58) = 2(130) = 260mTotal length of three rounds = 3*260 = 780m = 780/1000 = 0.78kmTime to make three rounds = Distance/Speed = 0.78/3 = 0.26 hours = 15.6mins
