Question 484751: The lengths of the sides of a triangle are in the ratio 5:6:7. Describe the length of the longest side if the perimeter is less than 54 centimeters. Please show your work. Answer by mananth(12270) (Show Source):
You can put this solution on YOUR website! ratio = 5:6:7
multiply by common factor x
the lengths are 5x , 6x, 7x
their sum = 18x
18x<54
x<3
then the longest side will be
7x<21
it will be less than 21
