Question

if length of diagonal of a rhombus whose area 216sq.cm. is 24cm. Then find length of second diagonal

Answer 1

Let the second length be y
area of rhombus=1/2xdiagonal1xdiagonal2
216=1/2x24xy
216=12y
y=216/12
y=18
the second length=18

Answer 2

given area = 216 sq.cm. and length of a diagonal is 24cm
area of rhombus = 1/2× d1×d2
then, 216 = 1/2 ×24×d2
        216 = 12×d2
        d2 = 18cm
