Question

Find the perimeter of a square field whose area is 49 hectares.

Answer 1

Area = 49 hectares or 490000 m²
We know that area of square = Side X Side = Side²
Therefore   Side² = 490000 m² 
                 √Side² = √490000 m²
                   Side  =   700 m
We know that perimeter of square =  4 X Side
  Therefore perimeter                     =   4 X 700 = 2800 m
