E.) 30

**Area of a rectangle = length x width**

**If the area is 54 and the length is 9, then the width would be 6.**

A = length x width

54 = 9w {substituted area, width, and length into area formula}

w = 6 {divided each side by 9}

**The perimeter of a rectangle = 2(width) + 2(length)**

P = 2(width) + 2(length)

P = 2(6) + 2(9) {substituted width and length into perimeter formula}

= 12 + 18 {multiplied}

= 30 {added}

Perimeter is 30 centimeters

**E.) 30**
