side(a)= 5 ft
\n" ); document.write( "area of equilateral triangle (A)= $\"+%28sqrt%283%29%2F4%29a%5E2\"$
\n" ); document.write( " = $\"+%28sqrt%283%29%2F4%295%5E2\"$
\n" ); document.write( " = $\"+%28sqrt%283%29%2F4%29%2A25\"$
\n" ); document.write( " = $\"sqrt%283%29%2A25%2F4\"$
\n" ); document.write( " = $\"+sqrt%283%29%2A6.25\"$
\n" ); document.write( " = $\"1.732%2A6.25\"$
\n" ); document.write( " =10.825 sq feet
\n" ); document.write( "1 foot =30 cm
\n" ); document.write( " = 10.825*30*30
\n" ); document.write( " =9742.5 square cm
\n" ); document.write( "result: 9742.5 square cm
