Question

the side of triangle are in ratio 2 :3 : 5 .if its perimeter is 100 cm the length of its smallest side is​

Answer 1

Answer:

Step-by-step explanation:

LET MULTIPLY THE RATIO BY X

ANSWER:

2X+3X+5X=100

10X=100

X=10

SMALLEST SIDE IS 20CM

Answer 2

Length of the smallest side is 20 cm

Given :

• The side of triangle are in ratio 2 : 3 : 5

• The perimeter is 100 cm

To find :

Length of the smallest side

Solution :

Step 1 of 2 :

Form the equation

Here it is given that side of the triangle are in ratio 2 : 3 : 5

Let the sides are 2x cm , 3x cm , 5x cm

Now it is given that perimeter is 100 cm

By the given condition

2x + 3x + 5x = 100

Step 2 of 3 :

Find the value of x

2x + 3x + 5x = 100

⇒ 10x = 100

⇒ x = 100/10

⇒ x = 10

Step 3 of 3 :

Find length of the smallest side

So the sides of the triangle are 20 cm , 30 cm , 50 cm

Hence length of the smallest side = 20 cm
