hope u can understand thank you sorry I have forgetten and written wrong and thank you for like to and follow me also u will get answer very soon

## To Find :

## Given :

Let the sides of triangle be 3x , 5x and 4x

✫Perimeter of triangle = sum of all sides.

➔ 3x + 5x + 4x = 480

➔ 12x = 480

➔ x = 480/12

➔ x = 40

Hence,

Sides of triangle are:-⇛ 3x

= 3 × 40

=

120 m⇛ 5x

= 5 × 40

=

200m⇛ 4x

= 4 × 40

=

160mHence,

All sides of triangle = 120m, 200m and 160m

Verification:perimeter of triangle = 480

⟶ 120 + 200 + 160 = 480

⟶ 320 + 160 = 480

⟶ 480 = 480

LHS = RHSHence, Verified.
