Question

the sides of a triangle are in the ratio 4:5:6. Find the sides of the triangle, if its perimeter is 660 cm.​

Answer 1

Step-by-step explanation:

The sides of triangle are in ratio 4:5:2,

Perimeter of triangle is 660 cm.

.

Let, sides of triangle be,

a = 4x

b = 5x

c = 2x

We know that,

Perimeter of triangle = sum of all three sides

=> 660 = 4x + 5x + 2x

=> 660 = 11x

=> = x

=> 60 = x

So,

sides of the triangle are:

{a = 4x = 4×60 = 240 cm}

{b = 5x = 4×60 = 300 cm}

{c = 2x = 4×60 = 120 cm}

Answer 2

Answer:

let the sides of the triangle be 4x , 5x ,6x .

Perimeter = sum of all sides

660cm = 4x + 5x + 6x

660cm = 15x

660/15 = x

44 = x

4 × 44 = 176

5 × 44 = 220

6 × 44 = 264

here it is correct answer ......
