Question

the three sides of a triangle are in ratio of 7:8:9 and perimeter is 240 find the sides.​

Answer 1

Answer:

• Sides of triangle 70,80,90.

Given:

• Sides of in the ratio of 7:8:9
• Perimeter = 240

Solution:

Let :-

• Sides of triangles be 7x, 8x, 9x

By the question,

Perimeter of triangle = 240

7x + 8x + 9x = 240

24x = 240

x = 240/24

x = 10

Sides of triangles:

• 7x = 7 × 10 = 70
• 8x = 8 × 10 = 80
• 9x = 9 × 10 = 90
