Area of Quadrilateral Formula Using Sides

When the sides of a quadrilateral and two of its opposite angles are given, we can find its area using the Bretschneider′s formula. Let us consider a quadrilateral whose sides are a, b, c, and d, and two of its opposite angles are θ1 1 and θ2 2 .

Answer 2

$\Huge\bf \rightarrow \mid\mathcal{\underline{ \purple{Answer}}} \mid$

$\Large \bf \over \rightarrow\mid \bf{\underline{ \orange{Perimeter \: = \: Sum \: \: of \: \: all \: \: sides}}} \mid$

2x-3y+5z+8x-9y+6z+3x+2y-7z+4x+7y-8z

2x+8x+3x+4x-3y-9y+2y+7y+5z+6z-7z-8z

17x-12y+9y+11z-15z

= 17x-3y-4z

Hence , the perimeter is 17x-3y-4z .
