Hi Kimberly, the equation for the perimeter of a rectangle is: P = 2L + 2W, were P is the perimeter, L is the length, and W is the width.
Substituting and solving for L gives:
196 = 2L + 2 * 45
2L = 196 - 90
2L = 106
L = 53
The length is 53 centimeters in length

each width of a rectangle= 45 cm. each length of rectangle=x. perimeter= add all sides. equation: 90+2x=196, 2x=196-90=106, 106÷2=53 ×=53 cm both sides of rectangle's length= 106 cm01/24/19
