Question

Trapezul ortodiagonal ABCD,cu AB||CD, are diagonalele AC=135cm si BD=96cm.Calculati aria trapezului ortodiagonal.

Answer 1

[tex]Aria\ oricarui\ patrulaterr\ cu\ diagonalele\ perpendiculare\ este\ data\\ de\ formula:\\ A=\frac{d_1*d_2}{2}\\ Deci:\\ A_{ABCD}=\frac{AC*BD}{2}\\ A_{ABCD}=\frac{135*96}{2}\\ A_{ABCD}=135*48=6480cm^2[/tex]
