Answer:

Question is, In the given figure,ABCD is a rhombus,AO=4cm and DO=3cm them,find the perimeter of the rhombus?

Answer is here perimeter of rhimbus=20cm.

Step-by-step explanation:

$abcd \: is \: a \: rhombus \: with \: \\ ao = 4cm \: and \: do = 3cm \\ we \: know \: that \: diagangle \: of \\ a \: rhombus \: are \: perpendicular \\ = >now \: in \: rightangle \: \\ triangle \: aod \\ {ad}^{2} = {ao}^{2} + {od}^{2} by \: pythagers \\ therorem. \\ = > {ad}^{2} = {4}^{2} + {3}^{2} = 16 + 9 \\ = > 25sq.cm \\ here \: perimeter \: of \: given \\ rhomus = 4 \times side \\ = > 4 \times 5 = 20cm.$
