Length of a rectangular field is 250m and width is 150m. Anuradha runs around this field 3 times. How far did she run?
How many times she should run around the field to cover a distance of 4km?
Given:
Length, l = 250 m
Breadth, b = 150 m
Perimeter of field = 2 × (l + b)
= 2 × (250 + 150)
= 2 × 400
= 800 m
So distance covered after running three times = 3 × 800
= 2400 m or 2.4 km
To cover a distance of 4 km, Anuradha should run = 4000 / 800
= 5 times.
