Given the area of the rhombus is 120-meter square then find the length of one of the diagonals if the other diagonal is of length 12 m.

Question: Given the area of the rhombus is 120-meter square then find the length of one of the diagonals if the other diagonal is of length 12 m.

Solution:
Since we know that,
Area of Rhombus = (1/2) × Diagonal₁ × Diagonal₂

Putting all the known values, we get
120 = (1/2) × Diagonal₁ × Diagonal₂
⇒ 240 = 12 × Diagonal₂
⇒ Diagonal₂ = 240/12
∴ Diagonal₂ = 20 m
