The perimeter of 3 squares is 28 cm, 36 cm and 48 cm respectively. What will be the area of the square having perimeter equal to sum of edges of 3 squares? (in sq.cm)
Let side of 3 squares be a, b and c cm respectively. => a = 28/4 = 7 cm => b = 36/4 = 9 cm => c = 48/4 = 12 cm Perimeter of new square = a + b + c = 28 => side = 28/4 = 7 cm Required area = side2 = 72 = 49 cm2.
