Answer 2

Answer:

The other diagonal will be 30 cm

Step-by-step explanation:

Area of rhombus =   diagonal ( 1 ) x diagonal ( 2 )

                                -------------------------------------------  

                                                     2

Substituting values: (letting the second diagonal be 'd')

120      =  8 x d

              ----------

                  2

120      = 4 x d  (By cutting 8 and 2)

120/4   = d

 30      = d

Therefore, your second diagonal is 30cm.
