Question

the area of a rectangular feild is 3584 m sq. and it's length is 64 m.A boy runs around the feild at the rate of 8km/h. How long will he take to go 5times around it?​

Answer 1

Answer:

12 minutes

Step-by-step explanation:

Area of the rectangular field = 3584 M2.

Length of the rectangular field = 64 Mtrs.

Area of rectangle = Length x Breadth

So 64 x Breadth = 3584

Breadth = 3584/64 = 56 Mtrs.

Total distance to be ran by the boy = 5 x Perimeter of the rectangula Field

= 5 x 2(Length + Breadth) = 5 x 2(64 + 56) = 10 x 120 = 1200 Mtrs.= 1.2 Kms.

Speed of the boy = 6 Kms/Hr

So the time the boy will take = 1.2/6 = 0.2 Hrs x 60 = 12 Mins.

Ans: 12 Mins.
