Answers
Explanation:
the shorter side be x and longer side be x+3
\tt{ \boxed{ \green{Area \: \: of \: \: Trapezium = \frac{1}{2} (a + b)h}}}

\begin{gathered} \bf \longmapsto \pink{92.4 = \frac{1}{2} \times 5.6 \times (2x + 3)} \\ \end{gathered}
⟼92.4=

×5.6×(2x+3)
\bf \longmapsto \pink{92.4 = 2.8(2x + 3)}⟼92.4=2.8(2x+3)
\begin{gathered} \bf \longmapsto \pink{ \frac{92.4}{2.8} = 2x + 3} \\ \end{gathered}
⟼
2.8
92.4
=2x+3
\bf \longmapsto \pink{33 = 2x + 3}⟼33=2x+3
\bf \longmapsto \pink{2x = 30}⟼2x=30
\bf \longmapsto \pink{x = 15}⟼x=15
\therefore \tt \red{shorter \: \: side \: = 15cm} \: \: and \: \red{longer \: \: side \: \: = 18cm}∴shorterside=15cmandlongerside=18cm
•°• The lengths of the two parallel sides is 15 cm and 18cm .
