Question

The length of the diagonals of a rhombus is in the ratio 4:3 if its area is 384 cm²,find its side .pls answer with steps

Answer 1

Answer:

This is your answer

first we find its diagonal then find its side

Step-by-step explanation:

Area of

Answer 2

Answer:

Answer:

Here ,

Let Diagonal 1 (d₁ ) = 4x

And Diagonal 2 (d₂ ) = 3x

_____________________

As we know that

Area of a rhombus = $\frac{1}{2}$× d₁ ₓ d₂

→ 384 =  $\frac{1}{2}$× 4x × 3x

→ 384 × 2 = 12x²

→ 768 = 12x²

→ x² =   $\frac{768}{12}$

→ 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
