The perimeter of a rhombus is 16 cm. Its area is 12 cm2. Find its altitude.

Let the length of each side of rhombus=a cmNow, perimeter of rhombus=16 cm4a=16a=164a=4So, length of each side of rhombus=4 cmLet the length of altitude of rhombus=x cmNow, area of rhombus=12 cm2altitude×corresponding side=12x×4=12x=124x=3Hence, altitude of the rhombus is 3 cm.
