d. A park 85 m long and 65 m broad has a jogging track all around it. If Kavita goes
10 rounds along the track, what is the least distance that she would have covered?
Answers
Take this understand that A park is in form of a rectangle shaped track. It's length is : 85m long and It's breadth is : 65m broad.
According to Question,
Kavita does 10 rounds around the whole track, which counts as perimeter . 1 round = 1 perimeter. So , kavita does total 10 rounds = 10 × perimeter of track.
Therefore, The perimeter = 2( l + b )
= 2( 85 + 65 )
= 2 × 150
= 300m
it means one round = 300m So, 10 rounds = 300 × 10 = 3000m = 3km.
Hence, The least distance that she have covered = 3km.
Answer:
3000m or 3km
Step-by-step explanation:
perimeter of the park
=2(l+b)
=2(85+65)
=2×150
=300m
If Kavita goes 10 rounds along the track, she will cover 10 times the perimeter
Therefore the distance covered by Kavita is
=10×300m
=3000m
=3km
