An octagon has an area of 100”, it’s [sic] side length is 5, find it’s [sic] apothem.
\n" ); document.write( "----------------
\n" ); document.write( "I assume you mean 100 square inches.
\n" ); document.write( "Assuming it's a regular octagon, each central angle is 45 degs, and the area of each triangle formed by the radii is 1/8 of the 100 sq inches = 12.5 sq inches.
\n" ); document.write( "--------------
\n" ); document.write( "Area = 12.5 = b*h/2 = 5*h/2 (h is the apothem)
\n" ); document.write( "h = 5
\n" ); document.write( "That won't work.
\n" ); document.write( "--------------
\n" ); document.write( "Area of an octagon with sides of 5 is
\n" ); document.write( " $\"ns%5E2%2Acot%28180%2Fn%29%2F4+=+8%2A25%2Acot%2822.5%29%2F4\"$
\n" ); document.write( "Area =~ 120.71 sq inches
\n" ); document.write( "It can't be an octagon with sides = 5 and area = 100.
\n" ); document.write( "-----------------
\n" ); document.write( "PS it's = it is \n" ); document.write( "

\n" );
