Question

the sides of a triangular plot are in the ratio 3:5:7 and it's perimeter is 300m. the sides of a triangle are​

Answer 1

Answer:

The sides of triangle are 60,100,140

Step-by-step explanation:

Perimeter of triangle = Sum of sides

300. = 3x+5x+7x

300. = 15x

x = 20m

3x = 3×20=60

5x = 5 ×20=100

7x = 7×20=140

Answer 2

Answer:

Sides are 60,140,100

Step-by-step explanation:

Let the number be a factor of x

So, it will be(3x:5x:7x)

Therefore

3x + 5x + 7x = 300

15x = 300

x = 300/15

x=20

So the sides are

1 side. = 3x = 3*20 = 60

2 side. = 5x = 5*20 = 100

3 side. = 7x = 7*20 = 140

Just to check:

60+140+100=300
