Question

A park is 145 m long and 78m wide. Reena jogs around it 5 times. How much distance does she covers?

Answer 1

Step-by-step explanation:

Perimeter of rectangle =2(l+b)

=2(120+80)

=2(200)

=400m

distance covered by the athlete in 1 round=400m

distance covered by the athlete in 5 rounds=400m*5=2000m

Answer 2

Answer:

1200 m

Step-by-step explanation:

Given : Amit runs around a rectangular park which is 120m long and 80m wide

To Find:  Find the distance he covers in 3 rounds.

Solution:

Formula of perimeter of rectangle = 2(length+breadth)

Distance covered in one round is perimeter

So, perimeter =  2(120+80)

                       =2(200)

                       =400m

So, the distance traveled in one round is 400 m

Distance traveled in 3 rounds = 400*3 =1200
