Question

The sides of a triangle are in ratio 7:8:9. If the perimeter of the triangle 408 cm, find its sides.​

Answer 1

Answer:

17

Step-by-step explanation:

Since , the ratios are not the exact values ...so let us assume that the sides are 7x , 8x and 9x

therefore,

sum of all sides = perimeter

7x + 8x + 9x = 408

24x = 408

x = 408/24

x = 17

Answer 2

7x+ 8x+ 9x= 408

24x = 408

x= 17

put value of x in all ratio .
