In the 9 x 12 room, there is a floor space of 9*12 feet or 3 x 4 yards (3 feet to a yard)
\n" ); document.write( "3*4 = 12 square yards
\n" ); document.write( "12 sq. yards * 18.50 per square yard = $222\r
\n" ); document.write( "\n" ); document.write( "Area is found by multiplying height by width:
\n" ); document.write( "Two walls are 9' high x 9' wide and two walls are 9'high x 12' wide\r
\n" ); document.write( "\n" ); document.write( "(2*9*9) + (2*9*12) = 162+216 = 378 square feet
\n" ); document.write( "350 square feet are in one gallon so you will need to purchase two gallons = $32.00 dollars\r
\n" ); document.write( "\n" ); document.write( "Total for room #1 = $254\r
\n" ); document.write( "\n" ); document.write( "Room 2
\n" ); document.write( "Same process\r
\n" ); document.write( "\n" ); document.write( "Walls: (2*9*14)+(2*9*16) = 540 sq. feet (2 gallons of paint = $32)
\n" ); document.write( "Floors: 14 * 16 = 224 square feet or 24.8 square yards (9 square feet in one yard) Round up to 25 square yards * 18.5 = $462.50\r
\n" ); document.write( "\n" ); document.write( "Total for room two = $494.50\r
\n" ); document.write( "\n" ); document.write( "Room 3\r
\n" ); document.write( "\n" ); document.write( "walls: (2*9*12)+(2*9*14) = 468 square feet - 2 gallons of paint = $32
\n" ); document.write( "carpet: (12*14=168 square feet or 18.67 square yards) Round up to 19 yards.
\n" ); document.write( "19*18.50 = $351.50
\n" ); document.write( "Total for room 3 = $383.50\r
\n" ); document.write( "\n" ); document.write( "Total for house = $383.50 + $462.50 + $254.00 = $1100.
