Notam baza mica - b
Notam baza mare - B
Notam inaltimea - h
[tex]A_{trapez} =\frac{(b+B)*h}{2}=\frac{(8+15)*6}{2}=\frac{23*6}{2}=\frac{138}{2}= 69 cm^{2}[/tex]
[tex]LM=\frac{b+B}{2} =\frac{8+15}{2} \frac{23}{2} =11,5 cm[/tex]
꧁Sper ca te-am ajutat!꧂

A=
[tex] \frac{b - b }{2} [/tex]
=>A=
[tex] \frac{15 - 8}{2} [/tex]
=> A = l.m × h => A = 11 × 6 => A =66cm²
