Question

perimeter of triangle is 60 CM if it's side are in the ratio 1:3:2 then find its smaller side​

Answer 1

Answer:

Step-by-step explanation:

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

A/Q, 6 x = 60

so

x = 10

Its smallest angle = 10.

Answer 2

Given :-

• Perimeter of triangle → 60 cm.
• Ratio of sides → 1 : 3 : 2$.$

Have to Find :-

• What's the smallest side.

Solution :-

As we know that perimeter of triangle is sum of its all sides.

From given we know the ratio.

So, let we consider the sides be " 1x " , " 3x " and " 2x " respectively.

Perimeter ⇒ a + b + c

a ⇒ " 1x "

b ⇒ " 3x "

c ⇒ " 2x "

Substituting the values in the formula.

⇒ 1x + 2x + 3x = 60

⇒ 6x = 60

⇒ x = 60/6

⇒ x = 10 cm

Therefore,

• First side = 1x = 1 × 10 = 10 cm.
• Second side = 3x = 3 × 10 = 30 cm.
• Third side = 2x = 2 × 10 = 20 cm.

Hence,

First side is the smallest one of measurement 10 cm.
