Answer» Correct Answer - Option 2 : 25 : 49 Given: The ratio of diagonals of squares is 5 : 7. Formula Used: Area of triangle = ½ × (Diagonal)2 Calculations: Let the diagonals of the square be 5x and 7x respectively. Area of Square1 = ½ × (5x)2 Area of Square2 = ½ × (7x)2 The ratio of their areas = ½ × (5x)2 : ½ × (7x)2 ⇒ 25 : 49 ∴ The ratio of areas of squares is 25 : 49. |
