Given :-
- The diagonals of the rhombus are in the ratio 4 : 7 and the area is 504 sq. cm.
---------------------------------------------------
To Find :-
- The length of the diagonals.
---------------------------------------------------
Let us assume :-
→ Smaller diagonal be 4x.
→ Bigger diagonal be 7x.
---------------------------------------------------
Formula used :-
★ Area of a rhombus = (D₁ × D₂)/2
Where,
D₁ = Smaller diagonal of the rhombus
D₂ = Bigger diagonal of the rhombus
Finding the diagonals :
⟿ (4x × 7x)/2 = 504
⟿ 28x² = 504 × 2
⟿ 28x² = 1008
⟿ x² = 1008/28
⟿ x² = 36
⟿ x² = 6²
⟿ x = 6
∴ Diagonals are :
➽ Smaller diagonal = 4x = (4 × 6) = 24 cm
➽ Bigger diagonal = 7x = (7 × 6) = 42 cm
