The length of a rectangle is three times longer than its width. the perimeter of the rectangle is 16 feet. if x represents the width of the rectangle in feet, which equation can be used to find its value? 3x x = 16 (3x)(x) = 16 3x 3x x x = 16 3x 3x x = 16

equationthat can be used to find the value of x in the rectangle will be 3x + 3x + x + x = 16.## What is
