Aflatio Aria si
linie mijlocie a treperului ABCD cu
bare more AB, dacă: A B = 12 cm
h = 6cm CD = 8 cm​

Answer 1

Răspuns:

$Arie$ $trapez$ = $\frac{ (B + b ) * h }{2} =$$\frac{(12 + 8 ) * 6 }{2}$ $= \frac{120}{2} = 60$ $cm$²

linie mijlocie = $\frac{B + b }{2}$= $\frac{12 + 8 }{2} = \frac{20}{2} = 10 cm$
