Question

The diagonal of a quadrilateral is 30cm in length of perpendiculars to it from the opposite verticesare 6.8cm and 9.6 cm find the area of the quadrilateral

Answer 1

we first find the area of triangles formed by diagonal.
So area of 1st triangle=
$\frac{1}{2} \times 30 \times 6.8 \\ = {102cm}^{2} \\ \\ now \: area \: of \: 2nd \: triangle = \frac{1}{2} \times 30 \times 9.6 \\ \\ = {144cm}^{2} . \\ \\ \\ so \: area \: of \: quadrilateral = 144 + 102 \\ \\ {246cm}^{2} . \\ \\ \\ f \: you \: liked \: my \: answer \: mark \: itas \: brainliest......$
