Question
The perimeter of 4 squares is 32 cm, 40 cm, 48 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)Solution
Let side of 4 squares be a, b, c and d cm respectively. => a = 32/4 = 8 cm => b = 40/4 = 10 cm => c = 48/4 = 12 cm => c = 56/4 = 14 cm Perimeter of new square = a + b + c + d = 44 => side = 44/4 = 11 cm Required area = side2 = 112 = 121 cm2.
