Question

The perimeter of a triangle is 540 m and its sides are in the
ratio 12 : 25 : 17

Answer 1

Answer:

let sides are 12x, 25x and 17x

now perimeter = 540m

sum of sides =540

12x+25x+17x= 540

54x=540

x=540/54=10

sides are 120, 250 and 170m

Answer 2

Answer:

The sides of the triangle are 120m, 250m, and 170m respectively.

Step-by-step explanation:

Here we have been given to find the value of the sides of the triangle which are in the respective ratio of 12:25:17

Now it has also been mentioned that the total perimeter of this triangle is 540m

Now let us assume the sides to be 12n, 25n, and 17n respectively and so we have:

12n + 25n + 17n = 540

⇒ 54n = 540

⇒ n = 540 ÷ 54

⇒ n = 10

Hence the sides are as follows:

12n = 12 × 10 = 120m

25n = 25 × 10 = 250m

17n = 17 × 10 = 170m

Hence the sides of the triangle are 120m, 250m, and 170m respectively.
