Question
The perimeter of 4 squares is 24 cm, 36cm, 40 cm, and 44
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 = 24/4 = 6 cm => b = 36/4 = 9 cm => c = 40/4 = 10 cm => c = 44/4 = 11 cm Perimeter of new square = a + b + c + d = 36 => side = 36/4 = 9 cm Required area = side2Â = 92Â = 81 cm2.
