Answer:
Answer:
Here ,
Let Diagonal 1 (d₁ ) = 4x
And Diagonal 2 (d₂ ) = 3x
_____________________
As we know that
Area of a rhombus = × d₁ ₓ d₂
→ 384 = × 4x × 3x
→ 384 × 2 = 12x²
→ 768 = 12x²
→ x² =
→ x² = 64
→ x = √64
→ x = 8
__________________
Then ,
d₁ = 4x = 4 × 8 = 32 cm
d₂ = 3x = 3 × 8 = 24 cm
________________
In each triangle formed in the rhombus the length of diagonals will become half
Let the side be y
By pythagoras theorm :
16² + 12² = y²
256 + 144 = y²
y² = 400
y = √400
y = 20 cm
