1.	To take around of a square field, Dev had to walk 40 meters. Find the side of the square field.
Answer» Distance walked in two round = 40 meter ∴ Distance walked one round = 40/2 = 20 meter Distance walked in one round is called perimeter Therefore perimeter of square field = 20 meter ∵ 4 × side = Perimeter Side = Perimeter/4 = 20/4 = 5 meter Therefore side of square field = 5 meter.

To take around of a square field, Dev had to walk 40 meters. Find the side of the square field.

Answer»

Distance walked in two round = 40 meter

∴ Distance walked one round = 40/2 = 20 meter

Distance walked in one round is called perimeter

Therefore perimeter of square field = 20 meter

∵ 4 × side = Perimeter

Side = Perimeter/4 = 20/4 = 5 meter

Therefore side of square field = 5 meter.
