To find the perimeter of a rectangle, you need to add up all four sides. The given dimensions of the rectangle are 12 ft. by 4 1/2 ft.
The length of one pair of opposite sides is 12 ft, while the width of the other pair is 4 1/2 ft. Since all four sides are equal in a rectangle, you can add these measurements together.
Summing up the lengths, 12 ft + 12 ft + 4 1/2 ft + 4 1/2 ft gives us a total perimeter of 33 ft.
