Question

How to find length of rhombus if diagonals are given?

Answer 1

You know that the diagonals bisect each other.

SO, In △ DMC

Sides DM and MC are 12 of BD and AC respectively.

Now you know the lengths of two sides containing the right angle in a right-angled triangle, you can easily find the third side i.e. AC by using the Pythagoras Theorm.

And all the sides of a rhombus are equal so you have your answer.
