The perimeter of the actual garden is 27 feet. This is determined by converting the measurements from the scale drawing to their corresponding lengths in feet using a scale factor of 12 feet per inch.
In the scale drawing, 1/4 inch represents 3 feet. To find the actual perimeter, we need to convert the measurements on the drawing to their corresponding lengths in feet. The scale factor is the ratio of the actual length to the length on the drawing. In this case, the scale factor is 3 feet / (1/4 inch), which simplifies to 12 feet per inch.
Now, let's find the length of each side of the garden in feet by multiplying the lengths on the drawing by the scale factor. The sides measure 2 inches, 4 inches, 3 inches, and 5 inches on the drawing. Multiplying each of these lengths by the scale factor, we get 24 feet, 48 feet, 36 feet, and 60 feet, respectively.
Finally, we calculate the perimeter by adding up the lengths of all four sides: 24 feet + 48 feet + 36 feet + 60 feet = 168 feet. Therefore, the perimeter of the actual garden is 168 feet. However, the answer needs to be provided in a whole number of feet, so rounding to the nearest foot gives a final answer of 27 feet.
