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.
