Question

the sides of a triangle are in the ratio 4:5:6. if the perimeter of the triangle is 30cm, find its sides​

Answer 1

Answer:

4 5 6 - 4x 5x 6x

Perimeter = Sum of all three sides of the triangle

30 = 4x + 5x + 6x

30 = 15x

x = 2

So sides are 4(2) = 8

5(2) = 10

6(2) = 12.

Answer 2

Answer:

sides of triangle are 8cm, 10cm, 12cm

Step-by-step explanation:

ratio of sides of triangle=4:5:6:=x

perimeter of triangle=sum of three sides

30cm=4x+5x+6x

15x=30

x=2cm

4x=8cm

5x=10cm

6x=12cm

sides of triangle are 8cm, 10cm, 12cm
