First, we need to determine the actual dimensions of the garden based on the blueprint measurements using the scale of 1 inch = 4 feet.

The blueprint shows:

  • Width = 3 inches
  • Length = 5 inches

Now, we can convert the dimensions from the blueprint to the actual size:

  • Actual width = 3 inches × 4 feet/inch = 12 feet
  • Actual length = 5 inches × 4 feet/inch = 20 feet

Next, since the actual garden is doubled in size, we need to double the length:

  • New length = 20 feet × 2 = 40 feet

Thus, the new length of the garden will be 40 feet.

The correct answer is c. 40 feet.
