The length of a rectangle with area 54 square centimeters is 9 centimeters. What is the perimeter of the rectangle
A.) 6 B.) 12 C.) 15 D,) 24 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 Ask Algebra House Comments are closed.
