Answer» ong>Answer: 200 m Step-by-step EXPLANATION: Dude its very EASY...just follow my steps Let the breadth be 'B' km Hence, length = 2 x b km Now as she is jogging 'around' the field, we will CONSIDER the perimeter not the area, So, Perimeter = 2 x (l + b) km = 2 x (2b + b) km = 6b km now, She jogged 5 times so, 5xperimeter A.T.P. =) 5 x 6b = 3 =) b = 3 / 30 =) b = 0.1 Thus, Breadth = 0.1 km = 100 m Length = 2 x 0.1 km = 200 m Hope it helps you buddy.... And don't forget to mark it as BRAINLIEST of you like it... |
