Here, AC = 22 cm, BM = 3 cm,

DN = 3 cm, and

BM⊥AC, DN⊥AC

Answer 1

the answer is in the photo

Answer 2

Area of quadrilateral = ar (∆ ABD ) + ar (∆ ADC )  

= 1/2 × AC× BM + 1/2 × AC × DAN

= 1/2 × 22 × 3 + 1/2 × 22 × 3  

=. 11 × 3 + 11 × 3

= 33 + 33

= 66

:. AREA OF QUADRILATERAL ABCD IS 66 cm² .
