If the lengths of the diagonals of rhombus are 16 cm and 12 cm. Then, the length of the sides of the rhombus is

(a) 9 cm (b) 10 cm (c) 8 cm (d) 20 cm

Solution:

(b) 10 cm

Clarification:

We realize that,

A rhombus is a basic quadrilateral whose four sides are of same length and diagonals are opposite bisector of one another.

As indicated by the inquiry, we get,

NCERT Exemplar Solutions Class 10 Maths Chapter 6 Ex. 6.1-3

As indicated by the inquiry,

\[AC\text{ }=\text{ }16\text{ }cm\text{ }and\text{ }BD\text{ }=\text{ }12\text{ }cm\]

∠AOB = 90°

∵ AC and BD separates one another

AO = ½ AC and BO = ½ BD

Then, at that point, we get,

AO = 8 cm and BO = 6 cm

Presently, in right calculated ∆AOB,

Utilizing the Pythagoras hypothesis,

We have,

\[\begin{array}{*{35}{l}}

   ~  \\

   AB2\text{ }=\text{ }AO2\text{ }+\text{ }OB2  \\

\end{array}\]

\[AB2\text{ }=\text{ }82\text{ }+\text{ }62\text{ }=\text{ }64\text{ }+\text{ }36\text{ }=\text{ }100\]

\[\begin{array}{*{35}{l}}

   \therefore AB\text{ }=\surd 100\text{ }=\text{ }10\text{ }cm  \\

   ~  \\

\end{array}\]

We realize that the four sides of a rhombus are equivalent.

Hence, we get,

one side of rhombus = 10 cm.
