Question

8. In a parallelogram. ABCD, if BC = 14 cm, CF = 9 cm, BG= 21 cm, find AB

​

Answer 1

Answer:

give diagram of this question

Answer 2

Answer:

area of parallelogram by taking CF as base and BC as altitude

area of parallelogram = base ×height

=21*14

=294cm²

given,

CF =9cm

i.e. CF is the height of the parallelogram, taking AB as an altitude

let AB be x

therefore

x*9=294

x=294/9

x=98/3 or 32⅔
