n A-frame cabin has a triangular front with a base of 30 ft and a height of 20 ft. If the front is to be glass that costs $3 per square foot, what will the glass cost?
\n" ); document.write( ":
\n" ); document.write( "you should know the formula for the area of a triangle A = \"1%2F2\"*b*h
\n" ); document.write( ":
\n" ); document.write( "They give you the base and the height
\n" ); document.write( "A = \"1%2F2\"*30*20
\n" ); document.write( "A = 300 sq ft
\n" ); document.write( ":
\n" ); document.write( "Find the cost of the glass:
\n" ); document.write( "Cost = 300*3 = $900
\n" ); document.write( ":
