उत्तर
Area of a rhombus = Area of a triangle Base of triangle = 24 cm and altitude = 16 cm
∴ Area = `1/2 "base" xx "altitude"`
= `1/2 xx 24 xx 16 = 192` cm2
∴ Area of rhombus = 192 cm2
one diagonal = 19.2 cm
second diagonal = `("Area" xx 2)/"one diagonal"`
= `(192 xx 2)/19.2 = (192 xx 10 xx 2)/192 = 20` cm
