The sides of an isosceles triangle are 27, 27, and 12yd long.
\n" ); document.write( " What is the area of the triangle?
\n" ); document.write( ":
\n" ); document.write( "We need to find the height of the triangle to find the area
\n" ); document.write( ":
\n" ); document.write( "Draw the triangle, with the base as 12 yd, draw the height, a perpendicular line from the center of the base, bisecting the top angle.
\n" ); document.write( "Note that you have two right triangles,
\n" ); document.write( "one leg is half the base, 6
\n" ); document.write( "one leg is the height h
\n" ); document.write( "one side is the hypotenuse, 27
\n" ); document.write( "Using pythag
\n" ); document.write( "6^2 + h^2 = 27^2
\n" ); document.write( "36 + h^2 = 729
\n" ); document.write( "h^2 = 729 - 36
\n" ); document.write( "h^2 = 693
\n" ); document.write( "h = \"sqrt%28693%29\" is the height of the triangle
\n" ); document.write( ":
\n" ); document.write( "A = \"1%2F2\"b*h
\n" ); document.write( "A = \"1%2F2\"*\"12%2Asqrt%28693%29\"
\n" ); document.write( "Using your calc
\n" ); document.write( "A = 157.949
\n" ); document.write( "A = 157.9 sq/yds
\n" ); document.write( "
\n" );
