Question

35. Ratio between lengths of sides of a triangle is 1:2:3. Find the lengths of its sides if its perimeter
is 24cm.​

Answer 1

Answer:

sides of ∆are 4cm, 8cm and 12cm respectively.

Step-by-step explanation:

let the sides of ∆ be x, 2x and 3x respectively

perimeter of ∆=24 cm

x + 2x +3x =24cm

6x=24 cm

x=24cm/6

x=4cm

2x=2×4 cm=8cm

3x=3×4cm=12cm

Answer 2

Answer:

hyy mate here is your answer.....

Ans- given.

ratio of lenghts - 1:2:3...

we can write it as x(1x), 2x, 3x.

perimeter : 24 cm....

now,A/Q.

=> perimeter of triangle = sum of all sides of triangle..

=>24 = x +2x+3x

=>24 = 6x

=>24/6 =x

=>4 =x

first sidr of triangle = 4cm

second side, =4×2= 8cm

third side= 3×4= 12 cm..... ans....

thanks for asking.....

hope this will help u.....
