To solve, we first need to figure out the area of the trapezoid, and then multiply that answer by $0.60 per sq ft. \r
\n" ); document.write( "\n" ); document.write( "Area of a trapezoid:
\n" ); document.write( " \"A+=+%28%28a%2Bb%29%2F2%29h\" \r
\n" ); document.write( "\n" ); document.write( "Where
\n" ); document.write( " a, b are the bases
\n" ); document.write( " and h is the height\r
\n" ); document.write( "\n" ); document.write( "Note that a,b, and h are all given in the problem statement:
\n" ); document.write( " a = 60
\n" ); document.write( " b = 75
\n" ); document.write( " h = 40\r
\n" ); document.write( "\n" ); document.write( " A = \"%28%2860%2B75%29%2F2%29+%2A+40\"
\n" ); document.write( " = 2700 sqft\r
\n" ); document.write( "\n" ); document.write( " C = cost of plywood = 2700 sqft * $0.60/sqft = $1620\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "
