ABC త్రిభుజం వైశాల్యం = 1/2 × BC × ఎత్తు

⇒ 80 = 1/2 × 10 × ఎత్తు

⇒ ఎత్తు = 16 సెం.మీ

మనకు తెలుసు PQRS చతురస్రం యొక్క భుజం = 

\(\frac{{{\rm{Base}}\; \times \;{\rm{Height}}}}{{\left( {{\rm{Base}}\; + \;{\rm{Height}}} \right)}}\)

⇒ చతురస్రం PQRS యొక్క భుజం =

\(\frac{{10\; \times \;16}}{{10\; + \;16}}\)

⇒ చతురస్రం PQRS యొక్క భుజం =

\(\frac{{160}}{{26}} = \frac{{80}}{{13}}{\rm{\;cm}}\)
