(a) 6 cm
(b) 12 cm
(c) 18 cm
(d) 24 cm

(d) is the answer
As one round will be equal to perimeter of the square, p=2×4=8cm
So, three rounds will be= 3×p
=3×8=24cm

Answer 2

Given - Side of the park

Find - Distance covered

Solution - (d) 24 cm is the distance covered by Shalini.

The perimeter of the square will be = 4*side.

The perimeter of the square = 4*2

The perimeter of the square = 8 centimetres

Total distance covered by Shalini = 3*perimeter of square
