If the area of a rhombus is 320 cm² and the length one of its diagonal is 40 cm, what is the length of the other diagonal?

• 18 cm

• 16 cm

• 12 cm

• 15 cm

Answer explanation

Let the length of the two diagonals be denoted by d₁ and d₂, respectively. Area = 320 cm², d₁ = 40 cm and d₂ is unknown Area of rhombus = (d₁ × d₂)/2 According to the question, we have, 320 = (40 × d₂)/2 320 = 20 × d₂ d₂ = 320/20 = 16 cm So, Option 2 is correct.
