HELPPP! The sides of a triangle are in a 2:3:4 ratio. What is the length of the longest side if the perimeter of the triangle is 63in?

OpenStudy (anonymous):

2x + 3x + 4x = 63 9x = 63 x = 7 2x = 14 3x = 21 4x = 28 so 28in is the longest side

OpenStudy (doc.brown):

\[2i+3i+4i=63\]\[9i=63\]\[i=7\] \[4i=?\]
