Question

The diagonals of rhombus are $24$ cm and $10$ cm. Then its perimeter is:

• A. $26$ cm
• B. $40$ cm
• C. $52$ cm
• D. $68$ cm

Answer 1

Answer: (C)

$52$ cm

Diagonals of a rhombus bisect each other at right angle

And diagonals of a rhombus are given as $24cm$ and $10cm$

Since they bisect each other at right angle, we have

Side of a rhombus $=\sqrt{{12}^2+5^2}=13$

$\Rightarrow$ perimeter $=4\times 13=52cm$
