The lengths of the sides of a triangle are in the extended ratio 3:7:8. The triangle’s perimeter is 72 in. What are the lengths of the sides?

Answer:
The sides of the triangle are :
24cm,28cm and 36cm
Explanation: The ration of lengths are: 6:7:9 Let the sides be denoted as:
6x,7x and 9x The perimeter =88cm 6x+7x+9x=88 22x=88x = [tex] \frac{88}{22} [/tex]x=4 The sides can be found as follows:
6x=6×4=24cm 7x=7×4=28cm 9x=9×4=36cm
