Question

plz give me answer fastly ​

Answer 1

$Given \: p , (p+1) \:and \: 13\:cm \: are \: 3 \\ sides \:of \: a \: triangle .$

$Perimeter \: of \: the \: triangle = 56\:cm$

$Sum \: of \: the \: 3 \:sides = 56$

$\implies p+ (p+1) + 13 = 56$

$\implies p+ p+1+ 13 = 56$

$\implies 2p = 56 - 14$

$\implies 2p = 42$

$\implies p = \frac{42 }{2}$

$\implies p = 21\:cm$

Therefore.,

$\red { Value \:of \:p } \green {= 21\:cm }$
