• # question_answer Length of a rectangular field is 250 m and width is 150 m. Anuradha runs around this fields 3 times. How far did she run? How many times she should run around the field to cover as distance of 4 km?

Given, length of rectangular field (l) = 250 m and width of rectangular field (b) = 150 m Perimeter of the fields $=2(l+b)$ $=2\,(250+150)\text{ }m$ $=(2\times 400)m$ $=800\,\,m$ $\because$ Distance covered in one round = perimeter of the fields$=800\text{ }m$ $\therefore$ Distance covered in three rounds $=3\times 800$$=2400\text{ }m$ Now, number of rounds to cover 4 km, i.e. 4000m $=\frac{4000}{800}=5$ [$\because$1km = 1000]                                                                                    Hence, she should run 5 times around the field to cover the distance of 4 km.
