\n" ); document.write( "h=height ; b=base=(1/2)h; A=area=49 sq m
\n" ); document.write( " $\"A=%281%2F2%29bh\"$ Substitute for b.
\n" ); document.write( " $\"A=%281%2F2%29%281%2F2%29%28h%29%28h%29\"$
\n" ); document.write( " $\"A%5D%281%2F4%29h%5E2\"$ Multiply each side by 4/
\n" ); document.write( " $\"4A=h%5E2\"$ Find the square root of each side.
\n" ); document.write( " $\"2sqrt%28A%29=h\"$ Put in value for A.
\n" ); document.write( " $\"2sqrt%2849m%5E2%29=h\"$
\n" ); document.write( " $\"2%287m%29=h\"$
\n" ); document.write( " $\"14m=h\"$ ANSWER 1: The height is 14 meters.
\n" ); document.write( " $\"b=%281%2F2%29h\"$
\n" ); document.write( " $\"b=%281%2F2%2914m\"$
\n" ); document.write( " $\"b=7m\"$ ANSWER 2: The base is 7 meters.\r
