N'ime ihe ọ bụla ga-ama, otu nke abụọ bụ n'ime ya ga-ama na-achọ, na ihe ọzọ ga-ama ga-ama na-achọ. Keduzi ka ị ga-ama na-achọ n'ime ose? <response>: The garden is 220 * 120 = 26,400 square feet.
The tilled land will take up half the area, and the trellises and raised beds will be the other half. Each half is 26,400 / 2 = 13,200 square feet.
The trellises will take up 1/3 of the remaining land, so the raised beds will take 1 - 1/3 = 2/3 of the remaining land.
So the total area of the raised bed area will be 13,200 square feet * (2 / 3) = 8,800 square feet.

The final answer: 8800.
