Question

What is the perimeter of the given figure.​

Answer 1

Answer:

3a+2s

Step-by-step explanation:

because a+(a+s) +(a+s)

=3a+2s

Answer 2

$\huge \fbox{Answer}$

$\large \underline{\underline{ \frak{ \color{red}Given::}}}$

${ \mapsto \sf{Side \: of \: the \: figure \: is \: {\bf a}, {\bf a + 5} \: and \: {\bf{a + 5}}. }}$

$\large \underline{\underline{ \frak{ \color{blue}To \: find::}}}$

$\leadsto \sf{Perimeter \: of \: the \: figure. }$

$\large \underline{\underline{ \frak{ \color{green}Formula \: used::}}}$

${ \rightarrow {\fbox{Perimeter \: of \: the \: figure = Sum of all sides}}}$

$\large \underline{\underline{ \frak{ \color{peru}Concept \: required::}}}$

$\sf{Here \: we \: observed \: that \: two \: sides} \\ \sf{ of \: figure \: is \: equal \: and \: third \: is \: \: \: \: \:} \\ \sf{differ.So, \: it \: is \: property \: of \: isoceles} \\ \sf{triangle. \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: }$

$\large \underline{\underline{ \frak{ \color{indigo}According \: to \: Question::}}}$

${ \sf {\implies{Perimeter \: of \: the \: figure = Sum \: of \: all \: sides}}}$

${ \sf {\implies{Perimeter \: of \: the \: figure ={\bf a} + {\bf a + 5} + {\bf{a + 5}}.}}}$

${ \sf {\implies{Perimeter \: of \: the \: figure = {\bf{3a + 10}}.}}}$

$\bf{Hence,}$

$\: \: \: \: \: \: \: \: \: \underline{ \sf {\fbox{Perimeter \: of \: the \: figure = {\bf{3a + 10}}.}}}$
