    The formula for the perimeter is \(P =2(\rm length + width)\).

    Since the length is \(15\) and the width is \(x\), we have this equation:\[2(15 + x) = 54\]Solve for \(x\).

    OK, so do you know that the perimeter is the sum of ALL sides?

    Notice that opposite sides in a rectangle are equal.|dw:1357571260853:dw|

    So the sum of sides will be \(15 + 15 + x + x\). But it is also given that the sum of all sides (perimeter) is \(54\).

    So solve the equation \(15 + 15 + x + x = 54\)?
