The area of rectangular field is 3584 m² and it's length is 64 m a boy runs around the field at the rate of 6 km/h how long will it take to go five times around it?
Answers
Answer:
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.

Answer:
Step-by-step explanation:
Area of rectangle = Length x breadth = 3584 m²
⇒ 64 m x breadth = 3584 m²
⇒ breadth = 3584 m² / 64 m
⇒ breadth = 56 m
Perimeter of rectangle = 2 ( L+b) = 2 ( 64m + 56m)
= 2 ( 120m)
= 240 m
which means to go one round around a rectangle he takes 6 km/ hour
⇒ 240 m -------- 6 km/hr
⇒ for 5 rounds i.e; 240 m x 5 = 1200 m -------- ?
5 rounds = (1200 m x 6 km/hr ) / 240 km
= 30 km / hr
