Yes, you are correct. The perimeter of a rectangle or square is equal to the sum of all its sides. In this case, the rectangle has a length of 45 and a width of 20. To find the perimeter, you add the length twice (45 + 45) and the width twice (20 + 20), and then sum them all up: 45 + 45 + 20 + 20 = 130 units. Thus, the perimeter of the rectangle is 130 units.
