Question

Diagonals of a quadrilateral are of lengths 10cm and 24cm. If the diagonals bisect each other

at right angles, find the length of each side of the quadrilateral. What special name can you give

to this quadrilateral ?​

Answer 1

Answer:

Let ABCD be the rhombus where, AC=10cm and BD=24cm

Let AC and BD intersect each other at O.Now, diagonals of rhombus bisect each other at right angles.

Thus, we have

AO=

×24=12cm

In right angled △AOB,

=169

∴ AB=13cm

∴ The length of each side of rhombus is 13cm.
