Question

Find the area

of these

quadrilaterals

(Fig 11.14).​

Answer 1

Answer:

if AB // CD the quadrilateral is a rhombus .

than only we can find area ..

in rhombus diagonals bisect each other ,

so,

D1 = 7*2 = 14

D2 = 6*2 = 12

Area = 1/2 * d1 * d2 = 1/2 * 12 * 14 = 84 cm ²

Answer 2

Answer:

Area = d1*d2/2

= 7*6/2

= 42/2

= 21 cm
