The perimeter of 4 squares is 28 cm, 36 cm, 40 cm and 56 cm respectively. What will be the area of the square having perimeter equal to sum of edges of 4 squares? (in sq.cm)
Let side of 4 squares be a, b, c and d cm respectively. => a = 28/4 = 7 cm => b = 36/4 = 9 cm => c = 40/4 = 10 cm => d = 56/4 = 14 cm Perimeter of new square = a + b + c + d = 40 => side = 40/4 = 10 cm Required area = side2 = 102 = 100 cm2.
