PLZ I NEED QUICK HELP!!! The lenght of a rectangle is equal to triple the width. Which system of equations can be used to find the dimensions of the rectangle if the perimeter is 86 centimeters?
We can represent the perimeter of a rectangle with [tex]2l + 2w = p[/tex] where l represents the lenght, and w represents the width, finally p the peramiter. [tex]l = 3w \\ 2l + 3w = 86[/tex]
