Let's put this into the area formula. The formula for the area of a triangle is $\"A=lw\"$ . A is area, l is length, and w is width. We already know the area, $\"1%2F2\"$ , and the length, $\"3%2F8\"$ , so let's plug that in.\r
\n" ); document.write( "\n" ); document.write( " $\"1%2F2=%283%2F8%29%2Aw\"$ \r
\n" ); document.write( "\n" ); document.write( "Now divide $\"3%2F8\"$ from both sides. Divide $\"1%2F2\"$ by $\"3%2F8\"$ . When we divide fractions, you flip the fraction you are dividing by and multiply it to the original fraction. So we multiply $\"1%2F2\"$ by $\"8%2F3\"$ .\r
\n" ); document.write( "\n" ); document.write( " $\"1%2F2%2A8%2F3=8%2F6\"$ \r
\n" ); document.write( "\n" ); document.write( "Simplify $\"8%2F6\"$ .
\n" ); document.write( " $\"4%2F3\"$ \r
\n" ); document.write( "\n" ); document.write( "Now we know that $\"w=4%2F3\"$ , so the width is 4/3 inches. Hope I helped! :) \n" ); document.write( "
