hello friend here is ur ans
plz follow me correctly
firstly given radius is 12cm
then we need to find the area of rhombus
, then we have area of rhombus= 1/2 (d1+d2)
where d1 and d2 are length of diagonals
(then for correct picture of problem im drawing the fig for it so plz refer the attachment
so then from the fig it will be clear that three points lie on circle and one at center
then from figure OQ=r =d======(1) ,. where d is diagonal respectively
then from the fig it will be quitely clear that , the triangles of the rhombus will be equilateral
from the fig the two triangles namely OPQ AND ORQ ARE equilateral
from equation 1 it is clear that two diagonals of rhombus are same as that of radii, where as other two are not, so
the length of other diagonals
= 2×altitude of the triangle ORQ = root 3× r
since we kNow that
area of rhombus= 1/2×d1×d2
hence (1/2) ×r×root3× r = area (from the fig)==(2)
since r=12cm
from equation 2 we have 1 /2×12×root 3×12=
72×root3 cm^2
hope ot hepls u
its too lengthy but plz accommodate it
if u wont get it plz comment on it
above mentioned attachment is given plz see it
