  1. 44 ft2
  2. 480 ft2
  3. 360 ft2
  4. 576 ft2
  5. N

Answers

  1. 1. C: 70'. To find the unknown distance ("A"), subtract the known widths from the total width of the property. The total width of the property is 117'. The other known widths are 20' and 27'. To find A, subtract 20' and 27' from 117'. A + 20' + 27' = 117'. A = 117' - 20' - 27' = 70'.

  2. . B: 22'. To find the unknown length ("B"), subtract the known lengths from the total length of the property. The total length of the property is 79'. The known lengths are 37' and 20'. To find B, subtract 37' and 20' from 79'. B + 20' + 37' = 79'. B = 79' - 20' - 37' = 22'.

  3. 3. A: 19'. To find the unknown length ("C"), subtract the known lengths from the total length of the property. The total length of the property is 79'. The known lengths are 18', 18', and 24'. To find C, subtract 18', 18', and 24' from 79'. C + 18' + 18' + 24' = 79'. C = 79' - 18' - 18' - 24' = 19'.

  4. 4. B: 480 ft2. To find the area of the manager's office, multiply the length of the office by the width of the office. The length of the office is 24'. The width of the office is 20'. Area of the manager's office = 24' - 20' = 480 ft2.

Mathematical Usage

Answer the following questions based on this information:

1 foot = 12 inches
1 gallon = 3.785 liters
1 gallon = 4 quarts
