Answer 1

(ii) area of the given quadrilateral,
 = 1/2 * d1 * d2
 = 1/2 * 7 * 6
 = 42 /2 
 = 21 cm²
therefore area of the quadrilateral = 8 cm²
 (iii) area of the given quadrilateral ,
  area of 1 triangle ,
= 1/2 * b * h
= 1/ 2 * 8 * 2 
= 8 cm²
therefore area of 2 such triangles ,
= 2 * 8
= 16 cm²
therefore area of that quadrilateral = 16 cm²
