Answer : 120 cm²

Solution :
________

Given that : Perimeter of rhombus = 52 cm

As we know that : Perimeter of rhombus = 4a

Now, according to the question :

4a = 52

=> a = 13 cm

By the Pythagoras theoram :

{(side)}^{2}  =  ( {\frac{d1}{2}})^{2} +(    { \frac{d2}{2} })^{2}  \\  \\  =  >  {(13)}^{2}  =  ({ \frac{24}{2} })^{2}  +  {( \frac{d2}{2} })^{2}  \\  \\  =  > 169 = 144 +   ({ \frac{d2}{2} })^{2}  \\  =  > 5 =  \frac{d2}{2}  \\  \\  =  > d2 = 10 \: cm \:

So, the length of other diagonal will be 10 cm.

Now, Area of rhombus :

 \frac{1}{2}  \times (d1 \times d2) \\  \\  =  >  \frac{1}{2}  \times 10 \times 24 \\  \\  =  > 120  \: {cm}^{2}

So, the area of rhombus will be 120 cm²
