hey \: mate \: here \: is \: ur \: answer \\ \\  \frac{ar(abc)}{ar(ade)}  =  \frac{ {bc}^{2} }{ {de}^{2} }  \\  \\  \frac{25}{49}  =  \frac{ {bc}^{2} }{ {14}^{2} }  \\  \\ in \: trapezium \: bced \\ ar(bced) =  \frac{1}{2} (bc + de) \times h \\  \\ given \:   ar(bced) = 24 \:  {cm}^{2}  \\ bc = 10 \: cm \\ de = 12 \: cm \\ 24 \:  {cm}^{2}  =  \frac{1}{2} (10 + 14) \times h \\  \\ h =  \frac{48}{10 + 14}  \\  \\ h =  \frac{48}{24}  \\ h = 2 \: cm \\ ar(bcd) =  \frac{1}{2} \times  d \times h \\  =  \frac{1}{2}  \times 10 \times h \\  \\ ar(bcd) = \:  10 {cm}^{2}  \\  \\ plzzz \: mark \: as \: brainliest
