1. Answer:

   34cm.

   Step-by-step explanation:

   Let the length of other diagonal of the rhombus be x.

   Area of the rhombus = 1/2(product of diagonals)

   => 240cm² = 1/2(30×x)

   => 240cm² = 30x/2

   => 240cm² = 15x

   => x = 240cm²/15

   => x = 16cm.

   Now,

   [tex] perimeter \: of \: rhombus \: \\ = > \sqrt{( {d1})^{2} + ( {d2})^{2} } [/tex]

   [tex] = > \sqrt{( {16})^{2} + ( {30})^{2} } \\ = > \sqrt{256 + 900} \: \: \: \: \: \: \: \\ = > \sqrt{1156} \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \\ = > 34cm \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: [/tex]
