Final answer:
The perimeter of the garden is 48 feet.
Step-by-step explanation:
The perimeter of a rectangle can be found by adding together the lengths of all four sides. In this case, the length of the garden is given as 4 yards. To convert yards to feet, you can use the fact that there are 3 feet in 1 yard, so the length of the garden in feet is 4 yards x 3 feet/yard = 12 feet. Similarly, if the width of the garden is also 4 yards, you can convert it to feet using the same conversion ratio to find that the width in feet is also 12 feet.
The perimeter of the garden is the sum of the lengths of all four sides: 12 feet + 12 feet + 4 yards (converted to feet) + 4 yards (converted to feet). To convert the yards to feet, you can multiply by 3, as mentioned earlier. So, the perimeter in feet is 12 feet + 12 feet + (4 yards x 3 feet/yard) + (4 yards x 3 feet/yard) = 12 + 12 + (4 x 3) + (4 x 3) = 12 + 12 + 12 + 12 = 48 feet.
