This question is very simple if you know what formula to use.
\n" ); document.write( "Because you are making a banner and need a certain amount of fabric, you are trying to find the area of the triangle that will act as the banner. The formula to find the area of a triangle is below:
\n" ); document.write( "let A=the area of the triangle
\n" ); document.write( "let h=the hight of the triangle
\n" ); document.write( "let b=the base of the triangle
\n" ); document.write( "A=\"%281%2F2%29%2Ah%2Ab\"\r
\n" ); document.write( "\n" ); document.write( "This formula works because a triangle is always half of a rectangle, and the formula for a rectangle is:
\n" ); document.write( "\"A=h%2Ab\"\r
\n" ); document.write( "\n" ); document.write( "Now, we can easily plug in the length of the height and base to find the triangle's area.\r
\n" ); document.write( "\n" ); document.write( "A=\"%281%2F2%29%2Ah%2Ab\"
\n" ); document.write( "A=\"%281%2F2%29%2A6%2A6\"
\n" ); document.write( "A=\"%281%2F2%29%2A36\"
\n" ); document.write( "A=\"18ft%5E2\"\r
\n" ); document.write( "\n" ); document.write( "The area is \"18ft%5E2\", but we need to know the area in square yards.
\n" ); document.write( "There are 3 feet per yard, so there are 9 square feet per square yard.
\n" ); document.write( "Therefore, if you divide our answer in square feet by 9, you will get our answer in square yards. 18 divided by 9 is 2.
\n" ); document.write( "There are 2 square yards of fabric needed.
\n" ); document.write( "
\n" );
