Length is a dimension of an object to describe how long the object is, and the area is length times width which defines the size of a closed region in a plane or two-dimensions.

The given data can be listed below,

• The length of an acre is,$l=\frac{1}{8}mi$.
• The width of an acre is,$w=\left(\frac{1}{10}\right)脳l=\frac{1}{80}mi$.
• The depth of an acre is,$d=1ft$.

Area of an acre can be given as,

$A=l脳w$

Here, l is the acre鈥檚 length, and w is the width of the acre.

Substitute values in the above expression,

Thus, an acre of the land area is$\frac{1}{640}{\mathrm{mi}}^2$, i.e., 640 acres to a square mile.

Conversion of a mile into the foot is given by,

From the above conversion, the number of square $\mathrm{ft}$ in an acre is given by,

Thus, the number of square feet in an acre is $43,560{\mathrm{ft}}^2$.

Gallon in one cubic foot can be given by,

$1{\mathrm{ft}}^3=7.477\mathrm{gal}$

From the above conversion,

Thus, the gallons in 1 acre-foot are $3.25脳{10}^5\mathrm{gal}$.

a) an acre of land comprises of${\left(\frac{1}{640}\right)}^{th}$.part of a square mile.

b) an acre of land comprises of $43,560{\mathrm{ft}}^2$

c) The number of gallons in 1 acre-foot are $3.25脳{10}^5\mathrm{gal}$.
