Answer:-

Length of diagonals are :- 24 , 48 cm.

Given:-

Area = 576cm²

To find :-

The length of other diagonals.

Solution :-

Let the diagonals be  d_1 , d_2

A/Q.

d_1 = \dfrac{d_2}{2}

Also, 2d_1 = d_2

Now,

Area of Rhombus is given by :-

\boxed{\sf{A = \dfrac{1}{2}\times d_1 \times d_2}}

put the given value,

 576 = \dfrac{1}{2} d_1\times d_2

576 \times 2 = d_1 \times d_2

1152 = d_1 \times d_2

Now,put the value of d2 .

1152 = d_1 \times 2d_1

 1152 = 2(d_1)^2

 \dfrac{1152}{2}=2(d_1) ^2

 576 = (d_1)^2

d_1 = \sqrt{576}

d_1 = 24 cm

d_2 = 2.d_1 \\d_2 = 2\times24

d_2 = 48cm
