Question

Sapna jogs around a square park of side 70m. One day she jogged around the park 5 times.how much did she jog in all?

Answer 1

4 x 70 x 5 = 1400 meters, assuming she made sharp 90 degree turns at the square's corners. Add a little more if you rounds the corner, like baseball players round the bases, running further than just the distance from one base to the next.
