Answer:
Less than 21 cm.
Step-by-step explanation:
Let x represent the multiplier.
We have been given that the lengths of the sides of a triangle are in the ratio 5:6:7. The perimeter of all sides of the triangle would be .
We have been given that the perimeter is less than 54 cm.
We can set this information in an inequality as:
Since the length of longest side is , so:
Therefore, the length of the longest side will be less than 21 cm.
length of the longest side is less than 21
5n+6n+7n=18n
18n<54
n<54/18
n<3
7*3=21( longest side. )
I believe your answer is -7/54
