Question

The perimeter of a triangle is 1500m and it's sides are in the ratio 3:5:7, then what will be the length of each side of the traingle.

Answer 1

Answer:

$\large\boxed{\sf{300\:m,500\:m,700\:m}}$

Step-by-step explanation:

The ratio of three sides is 3:5:7

Let the sides be 3x, 5x and 7x respectively.

Also, perimeter = 1500 m

.°. 3x + 5x + 7x = 1500

=> 15x = 1500

=> x = 1500/15

=> x = 100

Hence, length of sides are 300 m , 500 m and 700 m respectively.

Answer 2

Answer:

The length of the three sides are 300m,500m, and 700m.

Step-by-step explanation:

Let  common ratio be x

Therefore,the ratio is now 3x:5x:7x

Perimeter=1500 m

According to the problem,

3x+5x+7x=1500

15x=1500

x=100

Hence the three sides are

3x=3*100=300m

5x=5*100=500m

7x=7*100=700m
