The length of the side of a triangle are 3 consecutive odd numbers what is the length of the longest side if the p remeber is 57

Question

Assign the variables write the equation and solve 

 

Answer 1

I believe PERIMETER was the word intended for the number 57.

 

x-2, x, x+2 are the three sides and their sum is 3x.  3x = 57; x = 19.

 

The sides of the triangle are 17, 19 and 21 and the latter is the longest side.
