Answer 1

Explanation:

$\large \green{ \underline{answer}} \\ \\ \large \implies \green{ \boxed{d \: = \: 24cm}} \\ \\ \large \implies \orange{ \underline{ \underline{step \: . \: by \: . \: step \: . \: explanation}}} \\ \\ \large \implies \orange{ \underline{given}} \\ \\ \large \implies{area \: \: of \: \: trapezium \: = \: 744cm {}^{2} } \\ \\ \large \implies{length \: \: of \: \: parallel \: \: sides \: \: are \: \: 23cm \: \: and \: \: 39cm}$

$\large \implies\blue{ \underline{formula \: \: of \: \: area \: \: of \: \: trapezium}} \\ \\ \large \implies \blue{ \boxed{area \: \: of \: \: trapezium \: \: = \frac{1}{2} \: \times sum \: \: of \: \: parallel \: \: sides \: \: \times \: \: distance \: \: between \: \: them }} \\ \\ \large \implies{744 = \frac{1}{2} \times (23 + 39) \: \times \: \: d} \\ \\ \large \implies{744 \: = \frac{1}{2} \: \times 62 \: \times d } \\ \\ \large \implies{744 = 31d } \\ \\ \large \implies \therefore \orange{ \boxed{d \: = 24 \: cm}}$
