Answer 2

Answer:

Explanation:

Given :

• The sides of a triangle are in the ratio 5 : 3 : 7.
• Perimeter of the triangle is 90 cm.

To Find :

• The measure of its sides.

Solution :

Given that, The sides of a triangle are in the ratio 5 : 3 : 7.

Let, side of triangle be 5x , 3x and 7x.

We know that,

Perimeter of triangle = Sum of all sides

=> 90 = 5x + 3x + 7x

=> 90 = 15x

=> x = 90/15

=> x = 6

Now,

• First side = 5x = 5 × 6 = 30 cm
• Second side = 3x = 3 × 6 = 18 cm
• Third side = 7x = 7 × 6 = 42 cm

Hence :

The measure of its sides is 30 cm, 18cm and 42 cm respectively.
