1)  

 Area of a rhombus is 129 cm2. one of its diagonal is 14 cm. Find the length of the other diagonal.

Answer: 258 cm


SOLUTION 1 :

Given   :

Area = 129 cm2

diagonal(d1) =  14cm

Area of the rhombus   =   12 x d1 x d2 sq.uni

                          129    =   12 x 14 x d2

                   (2 x 129)14  =  d2

                            25814  = d2

                           18.4 cm  = d2

The length  of the other diagonal  =  18.4cm



2)  

 Area of a rhombus is 63 cm2. one of its diagonal is 9 cm. Find the length of the other diagonal.

Answer: 126 cm


SOLUTION 1 :

Given   :

Area = 63 cm2

diagonal(d1) =  9cm

Area of the rhombus   =   12 x d1 x d2 sq.uni

                          63    =   12 x 9 x d2

                   (2 x 63)9  =  d2

                            1269  = d2

                           14.0 cm  = d2

The length  of the other diagonal  =  14.0cm
