Question

the width


of a rectangle is 5 centimetre and is diagonal is 13 cm what is the IT perimeter​

Answer 1

$\textbf{\huge{ANSWER:}}$

$\tt{Given:}$

Width of rectangle = 5 cm
Diagonal measures = 13 cm

The figure of the question is attached above. Do see it !

By the Pythagoras Theorem in Triangle ABC:-

$H^{2} = P^{2} + B^{2}$

=》 $13^{2} = 5^{2} + x^{2}$ (Let the side be = x)

=》 $169 - 25 = x^{2}$

=》 $\sqrt{144} = x$

=》 $\textbf{x = 12 cm}$

Now that we know, both the sides of the rectangle, which are $\textbf{5 cm and 12 cm,}$ we can find the Perimeter.

Perimeter = 2 (l + b)

=》 P = 2 (5 + 12)

=》 P = 2 ( 17 )

=》 $\textbf{P = 34 cm}$
