Answer 2

Given -

Perimeter of triangle = 950 m

Ratio of sides = 6:9:4

To find -

Length of each sides.

Formula used -

Perimeter of triangle = a + b + c

Solution -

In the question, we are provided with the ratio of the sides of a triangle and it's Perimeter is 950 m², and we need to find the length of the sides. For that, first we will take a common ratio x then, we will apply the formula of perimeter of triangle, after that we will find the value of x, then will multiply the obtained with the ratio given.

Let -

The common ratio be x

So -

6 = 6x (Side a)

9 = 9x (side b)

4 = 4x (side c)

Perimeter = 950 m (as P)

Perimeter of triangle -

P = a + b + c

On substituting the values -

→ P = a + b + c

→ 950 m = 6x + 9x + 4x

→ 950 m = 19x

→ x = 950/19

→ x = 50

Now -

We will multiply the obtained value of x, with 6, 9 and 4 to find the length of each side.

→ 6x = 6 × 50 = 300 m

→ 9x = 9 × 50 = 450 m

→ 4x = 4 × 50 = 200 m

Verification -

→ P = a + b + c

→ 950 m = 300 m + 450 m + 200 m

→ 950 m = 750 m + 200 m

→ 950 m = 950 m

Therefore, the length of each side is 300m, 450m and 200m
