Question

The area of a trapezium is 13.5 sq cm and the perpendicular distance between its parallelsides is 3 cm . If the length of one of the parallel sides is 5.6 cm, fid the length of the other parallel side.

Answer 1

this is the answer 3.4cm

Answer 2

$hey \: mate \\ here \: is \: your \: answer \\ \\ the \: area \: of \: trapezium \\ \frac{1}{2} \times (the \: sum \: of \: parallel \: side) h \\ 13.5 = \frac{1}{2} (5.6 + x) \times 3 \\ 13.5 = \frac{5.6 + x}{2} \times 3 \\ 13.5 = \frac{16.8 + 3x}{2} \\ 27 = 16.8 + 3x \\ 3x = 27 - 16.8 \\ 3x = 10.2 \\ x = \frac{10.2}{3} = 3.4$
