Kamla :
The perimeter of the sqare is : side+ side+side+side =4x side
Perimeter=4x146 = 584 m
But she make 2 rounds, so she will run 584x2=1168 m

Sita :

The perimeter of the rectangular is:
length+length+width+width
Perimeter= 124+124+86+86
Perimeter=420

She runs also 2 rounds : 420x2=840 m

So Sita is the one who runs less.
840<1168
