The lot is 9.2% of the an acre.
Given:
Area of an acre = 4840 sq. yards
Area of lot = 40 by 100 ft = [tex]40 ]\times 100 = 4,000 $ ft^{2}[/tex]
To determine the the percentage of the acre of land that the lot will occupy, we would do the following:
Thus:
Convert the area of the lot to feet ([tex]9 ft^{2} = 1yd^{2}[/tex]):
Therefore:
Area of lot = [tex]\frac{4,000}{9} = 444.4 $ yd^{2}[/tex]
Percentage occupied by the lot = area of lot / area of acre x 100
[tex]= \frac{444.4}{4840} \times 100\\\= 9.2[/tex]
The lot therefore is 9.2% of the an acre.
