Question 329176: A standard rectangular highway billboard sign has a perimeter of 124 feet. The length is 6 more than three times the width. Find the dimensions of the sign.
perimeter is 124 ft
Let length = 3x + 6
let x= width
x+3x+6=124
4x+6=124
-6 -6
4x= 118
4x/4 118/4
x= 29.5
width = 29.5 ft, length = 3x29.5+6 or 94.5+6+ 100.5
29.5+100.5= 130 Where did I go wrong?
