Question

the sides of a triangle are in the ratio 2.2.3.if the perimeter of the triangle is 70 cm. find the length of each side of the triangle

​

Answer 1

Answer:

2x+2x+3x=70

7x=70x=10

hence,2x=2*10=20

2x=2*10=20

3x=3*10=30

hence lengths are20,20,30

Answer 2

Answer:

Let the sides be 2x, 2x and 3x.

Perimeter of a triangle = Sum of all sides

So,

70 = 2x + 2x + 3x

70 = 7x

7x = 70

x =70/7

x = 10

Now,

Side 1 = 2x = 2(10) = 20

Side 2 = 2x = 2(10) = 20

Side 3 = 3x = 3(10) = 30
