# Gary and Carolyn plan to build the deck shown.a) Find the total floor space (area) of the deck.b) Find the approximate cost of building the deck if the estimated cost is $6.40 per ft 2 . To determine a) To find: The total floor space (area) of the deck. Explanation Converting theoretical statement into mathematical statement, identifying the figure and the calculation is followed by suitable geometric formulae. Calculation: Given, Length of rectangular deck floor space l=(12+10)=22Â ft Width of the rectangular deck floor space w=10Â ft Total area of the rectangular deck To determine b) To find: The approximate cost of building the deck if the estimated cost is$6.40 per ft2.
