None, since there can be no conversion.
A linear (or lineal) foot is a measure of length in 1-dimensional space. An acre is a measure of area in 2-dimensional space. The two measure different things and, according to basic principles of dimensional analysis, any attempt at conversion from one to the other is fundamentally flawed.

An acre of land is equal to 43,560 square feet, so half an acre is 21,780 square feet. The dimensions of a half-acre plot can vary depending on the shape, but a common dimension for a half-acre plot is approximately 209 feet by 104 feet.
A half acre is equal to 21,780 square feet. In terms of dimensions, a half acre can be a square plot measuring approximately 147.6 feet on each side, or a rectangular plot measuring about 100 feet by 218.7 feet.
The actual dimensions of the acre can vary greatly as long as the total area is correct. It just has to contain 43560 square feet.
One third of an acre is approximately 14,520 square feet. Since an acre is 43,560 square feet, one third of that area can be represented in various dimensions, such as a rectangle measuring about 120 feet by 121 feet, or a square with each side measuring approximately 121 feet. The specific dimensions can vary depending on the shape you choose.

An acre is defined as any area that is 43,560 square feet, and therefore doesn't have any set dimensions as it can be in the shape of a square, rectangle, triangle, etc. However, the dimensions of an acre that is a perfect square is about 208. 71 feet by 208. 71 feet.
An acre was NOT defined as 43560 feet, but as 43560 SQUARE feet. This is immediately apparent when you consider that an acre is a measure of area, with dimensions [L2]. A foot is a measure of distance, with dimensions [L]. Basic dimensional analysis teaches that you cannot convert between measures with different dimensions without additional information. An acre is equivalent to the area of 1 furlong (660 feet) by 1 chain (66 feet).
An acre contains 43,560 square feet. Any combination of numbers that give you that area can be the dimensions. A square 209 feet by 209 feet is pretty close to an acre.

This question cannot be answered sensibly. An acre is a measure of area, with dimensions [L2]. A foot is a measure of distance, with dimensions [L]. Basic dimensional analysis teaches that you cannot convert between measures with different dimensions such as these without additional information.
A three-quarter acre is equivalent to 32,670 square feet. If you assume a rectangular shape, common dimensions could be approximately 150 feet by 215 feet. However, the dimensions can vary widely depending on the specific layout, as any configuration that maintains the total area of 32,670 square feet would qualify as three-quarters of an acre.
