Answer 2

Answer:

Hence, we know that diagonals of a square are equal, So, Length of the Both diagonals will be 13 cm.

Also, A Square is also a Rhombus.

Therefore,

Area of the Square (Rhombus) = $\frac{d_1d_2}{2}$

=> 13 × 13/2

=> 169/2

=> 84.5 cm²

Also, Area of Square = a²

Therefore,

=> a² = 84.5 cm²

=> a = √84.5 cm²

Hence, the side of the Rhombus is √84.5 cm²
