Question

The diagounal of a rhombus are 15cm and 36 cm. Find its perimeter.

Answer 1

Perimeter of rhombus d1 +d2=15+36=51

Answer 2

Hey!!


Let the side be x

Diagonal of rhombus are 15 cm and 36 cm ( given )


Hence the diagonal divided in two equal parts


Diagonal will be 7.5 cm and 18 cm

Now,

By using Pythagoras theorem

=> x^2 = ( 7. 5 ) ^2 + 18^2

=> x^2 = 56.25 + 324

=> x = √380

=> x = 19.5 ( approx )



Perimeter of rhombus = 4 × side

=> 4 × 19.5

=> 78 cm




Hope it will helps you!
